Abstract
PURPOSE This paper examines the subjective experience of medical interventions on intersex bodies to reduce cancer risk. METHODS Twenty-five individuals with intersex variations took part in semi-structured interviews, analysed through thematic discourse analysis. RESULTS Intersex bodies were positioned as inherently sick and in need of modification, with cancer risk legitimating surgical and hormonal intervention. This resulted in embodied shame, with negative impacts on fertility and sexual wellbeing. However, many participants resisted discourses of bio-pathologisation and embraced intersex status. Some medical interventions, such as HRT, were perceived to have increased the risk of cancer. Absence of informed consent, and lack of information about intersex status and the consequences of medical intervention, was positioned as a human rights violation. This was compounded by ongoing medical mismanagement, including health care professional lack of understanding of intersex variations, and the objectification or stigmatization of intersex people within healthcare. The consequence was non-disclosure of intersex status in health contexts and lack of trust in health care professionals. CONCLUSIONS The legitimacy of poorly-evidenced cancer risk discourses to justify medical intervention on intersex bodies needs to be challenged. Healthcare practitioners need to be provided with education and training about cultural safety practices for working with intersex people.

Abstract
Disorders of sex development (DSD) can be classified as 46,XX DSD, 46,XY DSD, and sex chromosome DSD. Several underlying causes including associated genes have been reported. Steroidogenic factor-1 is encoded by the NR5A1 gene, a crucial regulator of steroidogenesis in the growth of the adrenal and gonadal tissues. It has been discovered to be responsible for 10 to 20% of 46, XY DSD cases. Here, we described a 2-month-old infant who had ambiguous genitalia and 46, XY. Using whole exome sequencing followed by polymerase chain reaction-Sanger sequencing, a novel heterozygous nonsense c.1249C > T (p.Gln417Ter) variant in the NR5A1 gene was identified. It is present in his mother but absent in his father and maternal aunt and uncle. At the age of 7 months, the patient received a monthly intramuscular injection of low-dose testosterone for 3 months in a row. His penile length and diameter increased from 1.8 to 3 cm and from 0.8 to 1.3 cm, respectively. The patient also had normal adrenal reserve function by adrenocorticotropic hormone stimulation test. This study identified a novel causative p.Q417X (c.1249C > T) variant in NR5A1 causing 46,XY DSD in a Thai boy which is inherited from his unaffected mother.

PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0003568. [PMID: 39197054 PMCID: PMC11356455 DOI: 10.1371/journal.pgph.0003568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Accepted: 07/26/2024] [Indexed: 08/30/2024]
Abstract
Children with intersex variations continue to be subject to elective, irreversible, "sex-normalising" surgical interventions, despite multiple human rights and legislative bodies calling for their prohibition. Our systematic review aims to understand how medical literature reports rationales for "sex-normalising" surgical interventions conducted in childhood, and how they are contextualised within the medical and social controversy surrounding such interventions. PubMed, EMBASE and CINAHL were searched for English language, peer-reviewed articles reporting primary data on elective, genital, "sex-normalising" surgical interventions conducted on individuals <10 years, published 01/07/2006-30/06/2023 (PROSPERO ID: CRD42023460871). Data on outcomes reported, rationale for the conduct and timing of interventions and acknowledgement of controversy were extracted. Narrative synthesis described rationales and controversy. Risk of bias was assessed using Johanna Briggs Institute Tools. 11,042 records were retrieved, with 71 articles included for analysis. One of the most common outcomes collected in included literature were cosmetic outcomes, primarily reported by surgeons or parents. 62.0% of studies reported no rationale for intervention timing, 39.4% reported no rationale for conduct and 52.1% acknowledged no controversy in intervention conduct. Rationales included parental desire for intervention, anatomical/functional/cosmetic reasons, and a perceived goal of aligning with sex assigned by surgical teams or parents. Controversies addressed included concerns about the quality of interventions, the ethics of intervention conduct and gendered and social considerations. "Sex-normalising" interventions are conducted based largely on rationales that were not adequately supported by evidence, a desire from parents and surgeons to match genital cosmesis typically ascribed to male and female bodies, and a parental desire for intervention conduct. Legislating and medical regulatory bodies should advocate for ending the conduct of irreversible, elective, "sex-normalising" interventions conducted without the full, free and informed consent of the person concerned, to promote and protect the highest attainable standard of health for people with intersex variations.

[PMID: 39190944 DOI: 10.1016/j.anireprosci.2024.107579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Revised: 08/14/2024] [Accepted: 08/16/2024] [Indexed: 08/29/2024]
Abstract
Disorders of sex development (DSD) are congenital conditions characterized by atypical development of chromosomes, gonads, or anatomical sex. XX-DSD pigs disrupt the production of high-quality breeding pigs and impede the advancement of the pig industry. However, the etiology of XX-DSD pigs remains unclear. Systematic reports on the genetic and pathological characteristics of prepubescent XX-DSD pigs in familial contexts are sparse. This study aimed to investigate the genetic and pathological features of one-month-old XX-DSD pigs within a familial context and to provide phenotypic information to elucidate the pathogenic mechanisms of XX-DSD pigs. The findings revealed that inbreeding within the XX-DSD family may contribute to the pathogenesis of XX-DSD pigs. All XX-DSD pigs in the family had a chromosomal sex of female and were male pseudohermaphrodites. The degree of masculinization of the reproductive organs varied among XX-DSD pigs, demonstrating phenotypic heterogeneity. HE staining showed that the testes of prepubescent XX-DSD pigs contained vesicles in the seminiferous tubules, with or without vestigial germ cells. Ultrastructural analyses indicated that sertoli cells, leydig cells and germ cells in the testes of XX-DSD pigs exhibited pathological damage, confirming impaired testicular function. Immunofluorescence staining revealed high expression of SRY-box transcription factor 9 (SOX9) in XX-DSD pig testicular tissues, while forkhead box L2 (FOXL2) was minimally expressed. Disordered secretion of reproductive hormones in prepubescent XX-DSD pigs indicated abnormal hypothalamic-pituitary-gonadal axis (HPGA) function. This study elucidates the genetic and pathological characteristics of prepubescent XX-DSD pigs in familial case, providing valuable insights for further exploration of the pathogenic mechanisms underlying XX-DSD.

Evidence for NR2F2/COUP-TFII involvement in human testis development. Sci Rep 2024; 14:17869. [PMID: 39090159 PMCID: PMC11294483 DOI: 10.1038/s41598-024-68860-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Accepted: 07/29/2024] [Indexed: 08/04/2024] Open
Abstract
NR2F2 encodes COUP-TFII, an orphan nuclear receptor required for the development of the steroidogenic lineages of the murine fetal testes and ovaries. Pathogenic variants in human NR2F2 are associated with testis formation in 46,XX individuals, however, the function of COUP-TFII in the human testis is unknown. We report a de novo heterozygous variant in NR2F2 (c.737G > A, p.Arg246His) in a 46,XY under-masculinized boy with primary hypogonadism. The variant, located within the ligand-binding domain, is predicted to be highly damaging. In vitro studies indicated that the mutation does not impact the stability or subcellular localization of the protein. NR5A1, a related nuclear receptor that is a key factor in gonad formation and function, is known to physically interact with COUP-TFII to regulate gene expression. The mutant protein did not affect the physical interaction with NR5A1. However, in-vitro assays demonstrated that the mutant protein significantly loses the inhibitory effect on NR5A1-mediated activation of both the LHB and INSL3 promoters. The data support a role for COUP-TFII in human testis formation. Although mutually antagonistic sets of genes are known to regulate testis and ovarian pathways, we extend the list of genes, that together with NR5A1 and WT1, are associated with both 46,XX and 46,XY DSD.

Abstract
The nuclear receptor subfamily 5 group A member 1 (NR5A1) gene encodes NR5A1, also known as steroidogenic factor 1, a crucial transcriptional factor regulating adrenal and gonadal development and function. Although pathogenic variants in NR5A1 are known to cause a spectrum of disorders of sex development (DSD), individuals with 46,XY DSD with fully female internal and external genitalia are relatively rare. Herein, we present the case of a patient with 46,XY complete gonadal dysgenesis (CGD) who had a non-communicating rudimentary uterus due to a c.132_134del (p.Asn44del) heterozygous in-frame-deletion in NR5A1 that was diagnosed while treating a pelvic mass in which gynecological malignancy could not be disregarded. Unlike two previous cases with the p.Asn44del variant, this case presented with CGD, a severe DSD phenotype, and we found that the oligogenic inheritance of DSD-causative genes such as SRY, DHX37, SLC26A8, and CFTR may have affected the severity of the clinical phenotype.

Abstract
INTRODUCTION Achieving evidence-based, high-quality medical care is the overarching goal of healthcare quality management. Quality indicators (QIs) serve as proxies to show whether good quality is reached or not. This article describes the development of QI for the evaluation of healthcare quality in the area of differences of sex development (DSD). METHODS Following the model of Donabedian, the aim was to develop QI to assess defined relevant aspects of the quality of structures, processes, and outcomes of care in DSD. Ten DSD clinical centres and two self-advocacy groups in Germany included in the DSDCare project were involved in the development of the QI and a benchmarking system. The development of the QI involved several structured steps: analysis of guidelines and recommendations, literature review, qualitative interviews with key stakeholders in the field of DSD, and patients or their carers. QIs were discussed in a multi-stage systematic consensus process and assessed in terms of their relevance, feasibility, and practicability. RESULTS In a multi-stage systematic consensus process involving medical and psychological experts from a range of disciplines, people with DSD and their families, and representatives of self-advocacy groups, we have developed a set of 37 QIs (22 structure, seven process, and eight outcome quality). The QIs serve to evaluate care in the field of DSD and may add to the German criteria for certification of Centres for Rare Conditions formulated by the National Action League for People with Rare Diseases (NAMSE) in this area of expertise. CONCLUSION We have succeeded in developing and jointly adopting a set of QIs that consider a wide range of perspectives on the quality of care for people with DSD and their families. These QIs have been found to be relevant, feasible, and practicable, and they are now used for a yearly quality benchmarking in the participating DSD centres.

Abstract
Over the past century, genetics and genomics ("genomics") have contributed significantly to our knowledge of human biology and disease. Genomics has also bolstered inaccurate and harmful arguments about "essential" differences between socially defined groups. These purported differences have reinforced class hierarchies and justified the mistreatment of groups such as Black people, Indigenous people, and other people of color and/or people with disabilities. With this history in mind, we explore how genomics is used to reinforce scientifically unsound understandings of the relationship between two fundamental aspects of the human experience: sex and gender. We argue that imprecise, inaccurate practices for collecting data and conducting genomic research have adversely influenced genomic science and can contribute to the stigmatization of people whose sex and/or gender challenge binary expectations. The results have been to preclude transgender and intersex people from accessing high-quality, evidence-based healthcare and to hinder their participation in scientifically sound research. In this perspective, we use the lens of queer theory to render this situation more visible. First, we highlight the theoretical contributions queer theory can make to genomic science. Second, we examine practices in research and clinical genomics that exclude and stigmatize transgender and intersex people. Third, we highlight the ways that many current genomic research practices generate false conclusions that are used to support unjust public policies. We conclude by recommending ways that clinicians and researchers can-and should-harness the scientific, social, and cultural power of genomics to advance knowledge and improve lives across the spectra of sex and gender.

Abstract
Background Differences of Sex Development (DSD) are congenital conditions where the chromosomal, gonadal and anatomical sex characteristics do not strictly belong to male or female categories, or that belong to both at the same time. Surgical interventions for individuals with DSD remain controversial, among affected individuals, caregivers, and health-care providers. A lack of evidence in support of, for deferring, or for avoiding surgery complicates the decision-making process. This study explores Norwegian health-care professionals' (HCPs) perspectives on decision-making in DSD-related surgeries and the dilemmas they are facing in this process. Methods Focus group interviews with 14 HCPs integrated into or collaborating with multidisciplinary DSD teams were analyzed using reflexive thematic analysis. Results Two overarching dilemmas shed light on the intricate considerations and challenges that HCPs encounter when guiding affected individuals and caregivers through surgical decision-making processes in the context of DSD. The first theme describes how shared decision-making was found to be influenced by fear of stigma and balancing the interplay between concepts of normality, personal experiences and external expectations when navigating the child's and caregivers' needs. The second theme illuminated dilemmas due to a lack of evidence-based practice. The core concepts within each theme were the dilemmas health-care professionals face during consultations with caregivers and affected individuals. Conclusion HCPs were aware of the controversies with DSD-related surgeries. However, they struggled to reconcile knowledge with parents' wishes for surgery and faced dilemmas making decisions in the best interests of the child. This study draws attention to the benefits of increased knowledge on the consequences of performing or withholding surgery as well as incorporating tools enabling shared decision-making between HCPs and affected individuals/caregivers.

Abstract
PURPOSE Transition from pediatric to adult care is associated with significant challenges in patients with Turner syndrome (TS). The objective of the TRansition Age Management In Turner syndrome in Italy (TRAMITI) project was to improve the care provided to patients with TS by harnessing the knowledge and expertise of various Italian centers through a Delphi-like consensus process. METHODS A panel of 15 physicians and 1 psychologist discussed 4 key domains: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. RESULTS A total of 41 consensus statements were drafted. The transition from pediatric to adult care is a critical period for patients with TS, necessitating tailored approaches and early disclosure of the diagnosis to promote self-reliance and healthcare autonomy. Fertility preservation and bone health strategies are recommended to mitigate long-term complications, and psychiatric evaluations are recommended to address the increased prevalence of anxiety and depression. The consensus also addresses the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS; regular screenings and interventions are advised to manage these conditions effectively. In addition, cardiac abnormalities, including aortic dissections, require regular monitoring and early surgical intervention if certain criteria are met. CONCLUSIONS The TRAMITI consensus statement provides valuable insights and evidence-based recommendations to guide healthcare practitioners in delivering comprehensive and patient-centered care for patients with TS. By addressing the complex medical and psychosocial aspects of the condition, this consensus aims to enhance TS management and improve the overall well-being and long-term outcomes of these individuals.

[PMID: 38915825 PMCID: PMC11194351 DOI: 10.3389/fgene.2024.1387598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 05/14/2024] [Indexed: 06/26/2024] Open
Abstract
Differences/disorders of sex development (DSDs) in individuals with a 46, XY karyotype are a group of congenital disorders that manifest as male gonadal hypoplasia or abnormalities of the external genitalia. Approximately 50% of patients with 46, XY DSDs cannot obtain a molecular diagnosis. The aims of this paper were to review the most common causative genes and rare genes in patients with 46, XY DSDs, analyze global molecular diagnostic cohorts for the prevalence and geographic distribution of causative genes, and identify the factors affecting cohort detection results. Although the spectrum of genetic variants varies across regions and the severity of the clinical phenotype varies across patients, next-generation sequencing (NGS), the most commonly used detection method, can still reveal genetic variants and aid in diagnosis. A comparison of the detection rates of various sequencing modalities revealed that whole-exome sequencing (WES) facilitates a greater rate of molecular diagnosis of the disease than panel sequencing. Whole-genome sequencing (WGS), third-generation sequencing, and algorithm advancements will contribute to the improvement of detection efficiency. The most commonly mutated genes associated with androgen synthesis and action are AR, SR5A2, and HSD17B3, and the most commonly mutated genes involved in gonadal formation are NR5A1 and MAP3K1. Detection results are affected by differences in enrollment criteria and sequencing technologies.

Abstract
GCTs are developmental tumors and are likely to reflect ontogenetic and teratogenetic determinants. The objective of this study was to identify syndromes with or without congenital anomalies and non-syndromic defects as potential risk factors. Patients with extracranial GCTs (eGCTs) registered in MAKEI 96/MAHO 98 between 1996 and 2017 were included. According to Teilum's holistic concept, malignant and benign teratomas were registered. We used a case-control study design with Orphanet as a reference group for syndromic defects and the Mainz birth registry (EUROCAT) for congenital anomalies at birth. Co-occurring genetic syndromes and/or congenital anomalies were assessed accordingly. Odds ratios and 95% confidence intervals were calculated and p-values for Fisher's exact test with Bonferroni correction if needed. A strong association was confirmed for Swyer (OR 338.6, 95% CI 43.7-2623.6) and Currarino syndrome (OR 34.2, 95% CI 13.2-88.6). We additionally found 16 isolated cases of eGCT with a wide range of syndromes. However, these were not found to be significantly associated following Bonferroni correction. Most of these cases pertained to girls. Regarding non-syndromic defects, no association with eGCTs could be identified. In our study, we confirmed a strong association for Swyer and Currarino syndromes with additional congenital anomalies.

Abstract
The management of Differences of Sex Development (DSD) has evolved considerably in recent years. The questioning of systematic early childhood treatment of DSD requires a better understanding of the outcomes of such treatments and long-term studies are therefore essential to better evaluate the prognosis of DSD. Unfortunately, limitations are numerous including the limited size of the series, the absence of standardized methodology, the evaluation of managements that no longer take place today and the absence of prospective and comparative studies. Despite these difficulties, the purpose of this paper is to present the current data on the long-term follow-up of patients with DSD from the urological, sexual and fertility points of view. Even if it remains difficult at present to establish precise recommendations, we recapitulate the most important points that should drive follow-up of these patients especially the constitution of a multidisciplinary team with a holistic approach, the organization of the transition between adolescence and adulthood, a particular attention to psychological care, a careful communication with the patients and his/her family and the use of standardized data collection systems.

Abstract
The term 'differences of sex development' (DSD) refers to a group of congenital conditions that are associated with atypical development of chromosomal, gonadal, and/or anatomical sex. DSD in individuals with a 46,XX karyotype can occur due to fetal or postnatal exposure to elevated amount of androgens or maldevelopment of internal genitalia. Clinical phenotype could be quite variable and for this reason these conditions could be diagnosed at birth, in newborns with atypical genitalia, but also even later in life, due to progressive virilization during adolescence, or pubertal delay. Understand the physiological development and the molecular bases of gonadal and adrenal structures is crucial to determine the diagnosis and best management and treatment for these patients. The most common cause of DSD in 46,XX newborns is congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, determining primary adrenal insufficiency and androgen excess. In this review we will focus on the other rare causes of 46,XX DSD, outside CAH, summarizing the most relevant data on genetic, clinical aspects, puberty and fertility outcomes of these rare diseases.

Abstract
Gonad development includes sex determination and divergent maturation of the testes and ovaries. Recent advances in measuring gene expression in single cells are providing new insights into this complex process. However, the underlying epigenetic regulatory mechanisms remain unclear. Here, we profiled chromatin accessibility in mouse gonadal cells of both sexes from embryonic day 11.5 to 14.5 using single-cell assay for transposase accessible chromatin by sequencing (scATAC-seq). Our results showed that individual cell types can be inferred by the chromatin landscape, and that cells can be temporally ordered along developmental trajectories. Integrative analysis of transcriptomic and chromatin-accessibility maps identified multiple putative regulatory elements proximal to key gonadal genes Nr5a1, Sox9 and Wt1. We also uncover cell type-specific regulatory factors underlying cell type specification. Overall, our results provide a better understanding of the epigenetic landscape associated with the progressive restriction of cell fates in the gonad.

Abstract
BACKGROUND Human beings with a difference in sexual development (DSD) often underwent gender reassignment surgery during early childhood. However, the medical decision was often not congruent with the gender identity that affected persons developed later on. OBJECTIVES To represent the interests of affected persons, an interdisciplinary guideline in cooperation with support groups was written. MATERIALS AND METHODS The revision of the first version of the guideline, published in 2016, was edited by 18 professional societies and working groups as well as 3 support groups. A literature search was performed for each of the 12 chapters. Recommendations and statements created by the working groups were voted on during four consensus conferences. RESULTS The guideline highlights the right of self-determination of affected persons. In this context, new legal requirements are reported. Other than necessary primary diagnostics, medical procedures should be postponed. Most important is the psychological support of parents and patients. Tumor risk of the gonads and protection of fertility are analyzed and discussed in detail. CONCLUSION The content of the guideline represents a paradigm shift in dealing with human beings with a difference of sexual development. Projects as DSD Care and Empower-DSD help to promote the practical implementation of the guideline's recommendations.

Abstract
BACKGROUND Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency (21HD) can affect the in utero development of the genital anatomy of people with the 46XX karyotype. Health professionals engage parents in decision-making regarding managing genitals with this difference, including genital surgery options and patient communication. AIM We sought to investigate parental communication with their daughters regarding clitoral size variation related to neonatal CAH. METHODS Semistructured in-person interviews of 24 parents of chromosomal XX children with clitoral size variation attributable to a neonatal CAH diagnosis comprised 3 management categories: (1) clitoral reduction surgery (RS) (7 parents, 9 children), (2) clitoral concealment surgery (CS) (8 parents, 8 children), and no surgery on or around the clitoris (NS) (9 parents, 7 children). OUTCOMES Four representative themes, Obvious Choice, Still Different, Parental Burden, and Ignorance Is Bliss, were common across all 3 treatment groups. RESULTS For most parents, none of the 3 options of genital appearance alteration via clitoral reduction, clitoral concealment surgery, or avoidance of clitoral surgery ameliorated concerns, with most parents expressing an aversion to educating their child on the topic of genital differences, past treatment, or future function. CLINICAL IMPLICATIONS Reliance on surgical treatment pathways to manage this psychosocial concern is ineffective in alleviating parental uncertainty without the application of psychosocial interventions. STRENGTHS AND LIMITATIONS This was a qualitative study but was limited to parents of children with a specific genital difference, without direct exploration of parental values regarding the clitoris or the application of adequate psychosocial care. CONCLUSION Healthcare services must have an impact on parental ability to engage in essential communication with their children in cases such as clitoral size variation related to neonatal CAH. Improved communication skills allow parents to engage in more genuine decision-making and adapt to enduring genital reality, including possible future sexual challenges for their adult child, without resorting to burdensome strategies focused on attempts to perpetuate a benevolent ignorance.

Abstract
BACKGROUND Disorders/differences of sex development (DSD) are congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. With overlapping phenotypes and multiple genes involved, poor diagnostic yields are achieved for many of these conditions. The current DSD diagnostic regimen can be augmented by investigating transcriptome/proteome in vivo, but it is hampered by the unavailability of affected gonadal tissue at the relevant developmental stage. We try to mitigate this limitation by reprogramming readily available skin tissue-derived dermal fibroblasts into Sertoli cells (SC), which could then be deployed for different diagnostic strategies. SCs form the target cell type of choice because they act like an organizing center of embryonic gonadal development and many DSD arise when these developmental processes go awry. METHODS We employed a computational predictive algorithm for cell conversions called Mogrify to predict the transcription factors (TFs) required for direct reprogramming of human dermal fibroblasts into SCs. We established trans-differentiation culture conditions where stable transgenic expression of these TFs was achieved in 46, XY adult dermal fibroblasts using lentiviral vectors. The resulting Sertoli like cells (SLCs) were validated for SC phenotype using several approaches. RESULTS SLCs exhibited Sertoli-like morphological and cellular properties as revealed by morphometry and xCelligence cell behavior assays. They also showed Sertoli-specific expression of molecular markers such as SOX9, PTGDS, BMP4, or DMRT1 as revealed by IF imaging, RNAseq and qPCR. The SLC transcriptome shared about two thirds of its differentially expressed genes with a human adult SC transcriptome and expressed markers typical of embryonic SCs. Notably, SLCs lacked expression of most markers of other gonadal cell types such as Leydig, germ, peritubular myoid or granulosa cells. CONCLUSIONS The trans-differentiation method was applied to a variety of commercially available 46, XY fibroblasts derived from patients with DSD and to a 46, XX cell line. The DSD SLCs displayed altered levels of trans-differentiation in comparison to normal 46, XY-derived SLCs, thus showcasing the robustness of this new trans-differentiation model. Future applications could include using the SLCs to improve definitive diagnosis of DSD in patients with variants of unknown significance.

Abstract
A complete gonadal dysgenesis (CGD) with 46,XY karyotype is known as the Swyer syndrome and belongs to the group of 46,XY differences of sex development (DSD). The main problem in patients with Swyer syndrome is the delayed puberty and primary amenorrhea. Moreover, intrabdominal dysgenetic gonads in the patient with genetic material of a Y chromosome may conduce to the development of gonadal tumors, such as gonadoblastoma or germinoma. The management of such patients is based on preventive excision of dysgenetic gonads and long-term hormonal replacement therapy. Sporadic cases are considered more common than familial cases. This paper presents two siblings with Swyer syndrome in whom gonadoblastoma was found. A thorough review of familial CGD with 46,XY DSD in the literature from the last 15 years suggests that the risk of gonadal tumors could be increased in familial compared to sporadic cases (66.6% vs. 15-45%, respectively).

Gramc M. Challenges in Transition of Care for People with Variations in Sex Characteristics in the European Context. Healthcare (Basel) 2024; 12:354. [PMID: 38338239 PMCID: PMC10855080 DOI: 10.3390/healthcare12030354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 01/26/2024] [Accepted: 01/29/2024] [Indexed: 02/12/2024] Open
Abstract
OBJECTIVE People with variations in sex characteristics (VSCs) have been receiving inadequate care for many decades. The Chicago consensus statement in 2006 aimed to introduce improved comprehensive care, which would include the transition of care from pediatric to adult services organized by multidisciplinary teams. Yet, the evidence for transitional care is scarce. The aim of this paper is to outline the delivery of transition of care for adolescents and young adults with VSCs. METHOD Seven focus groups were conducted with health care professionals and peer support groups by care teams in Central, Northern, and Western Europe. The data from the focus groups were examined using reflexive thematic analysis. RESULTS Even though the transition of care has been implemented in the last two decades, it remains inadequate. There are differences among countries, as the quality of care depends on available resources and variations in sex characteristics. Moreover, there are significant hurdles to adequate transition of care, as there is lack of time and funding. The lack of adult care providers and psychosocial support often leaves young adults with VSCs to navigate the health care system alone. CONCLUSION The outcome of the study shows that the transition of care is organized through the department of pediatric endocrinology. The quality of care varies due to resources and variations in sex characteristics. A lack of adult specialists, and especially psychosocial support, represents the biggest obstacle for young adults and adults in navigating the health care system and for improvements in the provision of health care to adults. There is a risk of re-traumatization, as adolescents and young adults must often repeat their medical history and educate adult care providers who are insufficiently trained and knowledgeable.

Abstract
Ovotesticular disorder of sex development (OT-DSD) is a rare condition characterized by the presence of both ovarian and testicular tissue in the gonads. Management and sex designation of these patients depend on several factors, and an underlying potential for gender dysphoria should be acknowledged. We present a case of a patient diagnosed with 46,XX OT-DSD at 12 months old who was attributed a female sex designation but started manifesting gender dysphoria during adolescence. Gender identity is an important factor to consider on long-term follow-up of OT-DSD patients.

[PMID: 37781900 DOI: 10.1016/j.gim.2023.100987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/22/2023] [Accepted: 09/24/2023] [Indexed: 10/03/2023] Open
Abstract
PURPOSE To assess the population-based incidence, prevalence, and age at diagnosis of individuals with 45,X/46,XY mosaicism (and associated variants) and describe the associated mortality pattern. In addition, a systematic literature review of papers providing prevalence data of 45,X/46,XY mosaicism was performed. METHODS A population-based epidemiological study of all individuals diagnosed with 45,X/46,XY mosaicism between 1960 and 2019. Mortality was analyzed using data from the Danish Causes of Death Register. One-hundred randomly age- and sex-matched general population controls per case were identified for comparison. RESULTS One-hundred-thirty-seven males and 46 females with 45,X/46,XY mosaicism were identified. The apparent prevalence was 5.6 per 100,000 liveborn males and 2.1 per 100,000 liveborn females. The incidence of males with 45,X/46,XY increased during the study (P > .0001) but was stable for females (P = .4). Males were significantly older than females when diagnosed (median age = 29.1, interquartile range: 3.4-41.3) years versus 13.3 (interquartile range: 2.1-19.1) years, P = .002). All-cause mortality was doubled in males with 45,X/46,XY (Hazard Ratio = 2.0, 95% confidence interval: 1.2-3.3) and quadrupled in females (Hazard Ratio = 4.0, confidence interval: 2.0-7.9). CONCLUSION The apparent population-based prevalence of males and females with 45,X/46,XY is 5.6 and 2.1 per 100,000 liveborn males and females, respectively. Diagnosis of males with 45,X/46,XY males is increasing. 45,X/46,XY mosaicism is associated with an increased all-cause mortality.

Abstract
PURPOSE Differences of sex development (DSD) are congenital conditions that involve variations in individuals' sex chromosomes, genes, external and/or internal genitalia, hormones, and/or secondary sex characteristics. This study sought to elucidate the experiences of adolescents and young adults living with DSD by focusing on their experiences of intimacy and sexual health. METHODS An interpretative phenomenological research design was adopted. Semi-structured qualitative interviews were conducted with 11 Norwegian adolescents and young adults aged 16-26 years who had five different DSD conditions. The interview findings were analysed by means of a reflexive thematic analysis. RESULTS The participants reported feeling different, both in terms of how their body functioned and how their body looked. Lack of knowledge increased this feeling of differentness. Moreover, lack of everyday language with which to talk about intimacy and sexual concerns resulted in the participants feeling stigma. Anticipating stigmatization and lacking everyday language complicated the participants' communication regarding their DSD and sexual health. CONCLUSIONS The sexual experiences of adolescents and young adults with DSD are diverse. Fear of stigmatization and lack of everyday language complicate communication with healthcare professionals and others. Understanding their unique needs is crucial to helping individuals achieve good sexual health.

Abstract
PURPOSE Androgen insensitivity syndrome (AIS) is a disorder characterized by peripheral androgen resistance due to androgen receptor mutations in subjects with 46 XY karyotype. The severity of hormone resistance (complete, partial or mild) determines the wide spectrum of phenotypes. METHODS We performed a literature review on Pubmed focusing on etiopathogenesis, molecular alterations, and diagnostic-therapeutic management. RESULTS AIS is determined by a large variety of X-linked mutations that account for the wide phenotypic spectrum of subjects; it represents one of the most frequent disorders of sexual development (DSD). Clinical suspicion can arise at birth in partial AIS, due to the presence of variable degrees of ambiguity of the external genitalia, and at pubertal age in complete AIS, due to the development of female secondary sex characteristics, primary amenorrhea, and absence of female primary sex characteristics (uterus and ovaries). Laboratory tests showing elevated LH and testosterone levels despite mild or absent virilization may be helpful, but diagnosis can be achieved only after genetic testing (karyotype examination and androgen receptor sequencing). The clinical phenotype and especially the decision on sex assignment of the patient, if the diagnosis is made at birth or in the neonatal period, will guide the following medical, surgical and psychological management. CONCLUSIONS For the management of AIS, a multidisciplinary team consisting of physicians, surgeons, and psychologists is highly recommended to support the patient and his/her family on gender identity choices and subsequent appropriate therapeutic decisions.

Abstract
Background Complications are frequently reported after hypospadias repair and there is a need to understand the factors that influence their occurrence. Methods Data from boys with hypospadias born between 2000 and 2020 were obtained from the International Disorders of Sex Development (I-DSD) Registry. Logistic regressions, fisher's exact tests and spearman's correlation tests were performed on the data to assess associations between clinical factors and complication rates. Results Of the 551 eligible boys, data were available on 160 (29%). Within the cohort, the median (range) External Masculinization Score (EMS) was 6 (2, 9). All presented with one or more additional genital malformation and 61 (38%) presented with additional extragenital malformations. Disorders of androgen action, androgen synthesis and gonadal development were diagnosed in 28 (18%), 22 (14%) and 9 (6%) boys, respectively. The remaining 101 (62%) patients were diagnosed as having non-specific 46,XY Disorders of Sex Development. Eighty (50%) boys had evidence of abnormal biochemistry, and gene variants were identified in 42 (26%). Median age at first hypospadias surgery was 2 years (0, 9), and median length of follow-up was 5 years (0, 17). Postsurgical complications were noted in 102 (64%) boys. There were no significant associations with postsurgical complications. Conclusions Boys with proximal hypospadias in the I-DSD Registry have high rates of additional comorbidities and a high risk of postoperative complications. No clinical factors were significantly associated with complication rates. High complication rates with no observable cause suggest the involvement of other factors which need investigation.

Abstract
Background Differences of sex development (DSD or disorders of sex development) are uncommon congenital conditions, characterized by atypical development of chromosomal, gonadal, or anatomic sex. Objective Dermatologic care is an important component of the multidisciplinary care needed for individuals with DSD. This article discusses the most common primary dermatologic manifestations of DSD in addition to the cutaneous manifestations of hormonal and surgical therapies in individuals with DSD. Data sources Published articles including case series and case reports on PubMed. Study selections Selection was conducted by examining existing literature with a team of multidisciplinary specialists. Methods Narrative review. Limitations This article was not conducted as a systematic review. Results In Klinefelter syndrome, refractory leg ulcers and incontinentia pigmenti have been described. Turner syndrome is associated with lymphatic malformations, halo nevi, dermatitis, and psoriasis. Virilization can be seen in some forms of congenital adrenal hyperplasia, where acne and hirsutism are common. Conclusion Dermatologists should consider teratogenic risk for treatments of skin conditions in DSD depending on pregnancy potential. Testosterone replacement, commonly used for Klinefelter syndrome, androgen insensitivity syndrome, 5-alpha reductase deficiency, gonadal dysgenesis, or ovotesticular DSD, may cause acne.

Abstract
This article explores how race, sex, and gender are better thought of as a continuum rather than binary categories. Starting with a discussion of intersectionality, we examine the importance of ethnic-racial identity and explore unique cultural considerations for working with Black, Latinx, and AAPI transgender and nonbinary youth. We then examine intersex youth and variations of sex development, as well as specific challenges they face. Finally, we explore nonbinary gender identities and the importance of individually tailoring affirming interventions. For all sections, we highlight the strengths and resilience of the youth and offer clinical recommendations for child and adolescent providers.

Abstract
Diagnosis and management strategy of disorders of sex development (DSD) are difficult and various due to heterogeneous phenotype and genotype. Under widespread use of genomic sequencing technologies, multiple genes and mechanisms have been identified and proposed as genetic causes of 46,XY DSD. In this study, 178 46,XY DSD patients were enrolled and underwent gene sequencing (either whole-exome sequencing or targeted panel gene sequencing). Detailed clinical phenotype and genotype information were summarized which showed that the most common clinical manifestations were micropenis (56.74%, 101/178), cryptorchidism (34.27%, 61/178), and hypospadias (17.42%, 31/178). Androgen synthesis/action disorders and idiopathic hypogonadotropic hypogonadism were the most frequent clinical diagnoses, accounting, respectively, for 40.90 and 21.59%. From all next-generation sequencing results, 103 candidate variants distributed across 32 genes were identified in 88 patients. The overall molecular detection rate was 49.44% (88/178), including 35.96% (64/178) pathogenic/likely pathogenic variants and 13.48% (24/178) variants of uncertain significance. Of all, 19.42% (20/103) variants were first reported in 46,XY DSD patients. Mutation c.680G>A (p.R227Q) on SRD5A2 (steroid 5-alpha-reductase 2) (36.67%, 11/30) was a hotspot mutation in the Chinese population. Novel candidate genes related to DSD (GHR (growth hormone receptor) and PHIP (pleckstrin homology domain-interacting protein)) were identified. Overall, this was a large cohort of 46,XY DSD patients with a common clinical classification and phenotype spectrum of Chinese patients. Targeted gene panel sequencing covered most of the genes contributing to DSD, whereas whole-exome sequencing detected more candidate genes.

Gabriele A, Chierto E, Gino S, Inturri S, Aneli S, Robino C. Privacy and ethical challenges of the Amelogenin sex test in forensic paternity/kinship analysis: Insights from a 13-year case history. Forensic Sci Int Synerg 2023; 7:100440. [PMID: 37840559 PMCID: PMC10568343 DOI: 10.1016/j.fsisyn.2023.100440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 09/07/2023] [Accepted: 09/14/2023] [Indexed: 10/17/2023]
Abstract
The Amelogenin sex test included in forensic DNA typing kits has the potential to identify congenital conditions such as differences/disorders of sex development (DSD). It can also reveal mismatches between genotypic sex and gender marker in identity documents of transgender persons who obtained legal gender recognition. In a 13-year case history of paternity/kinship tests, involving n = 962 females and n = 1001 males, two mismatches between Amelogenin sex test (male) and gender marker (female), and three cases of chromosomal DSD (Klinefelter syndrome) were observed. The concrete risk of observing Amelogenin anomalies, their potential causes, and the context in which they occur (forensic, i.e. non-medical) mean that laboratory operators are called to strike a complex balance between privacy interests and individual health rights when providing preliminary information and reporting Amelogenin incidental findings. This case history argues for the need of a more responsible approach towards the Amelogenin sex test in the forensic community.

Lessons Learned from 17 Years of Multidisciplinary Care for Differences of Sex Development Patients at a Single Indonesian Center. Sex Dev 2023; 17:170-180. [PMID: 37699373 PMCID: PMC11232949 DOI: 10.1159/000534085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Accepted: 09/08/2023] [Indexed: 09/14/2023] Open
Abstract
BACKGROUND Our multidisciplinary team (MDT) is a large specialized team based in Semarang, Indonesia, that cares for a wide variety of pediatric and adult individuals with differences of sex development (DSD) from across Indonesia. Here, we describe our work over the last 17 years. METHODS We analyzed phenotypic, hormonal, and genetic findings from clinical records for all patients referred to our MDT during the period 2004-2020. RESULTS Among 1,184 DSD patients, 10% had sex chromosome DSD, 67% had 46,XY DSD, and 23% had 46,XX DSD. The most common sex chromosome anomaly was Turner syndrome (45,X) (55 cases). For patients with 46,XY DSD under-masculinization was the most common diagnosis (311 cases), and for 46,XX DSD, a defect of Müllerian development was most common (131 cases) followed by congenital adrenal hyperplasia (CAH) (116 cases). Sanger sequencing, MLPA, and targeted gene sequencing of 257 patients with 46,XY DSD found likely causative variants in 21% (55 cases), with 13 diagnostic genes implicated. The most affected gene codes for the androgen receptor. Molecular analysis identified a diagnosis for 69 of 116 patients with CAH, with 62 carrying variants in CYP21A2 including four novel variants, and 7 patients carrying variants in CYP11B1. In many cases, these genetic diagnoses influenced the clinical management of patients and their families. CONCLUSIONS Our work has highlighted the occurrence of different DSDs in Indonesia. By applying sequencing technologies as part of our clinical care, we have delivered a number of genetic diagnoses and identified novel pathogenic variants in some genes, which may be clinically specific to Indonesia. Genetics can inform many aspects of DSD clinical management, and while many of our patients remain undiagnosed, we hope that future testing may provide answers for even more.

Abstract
Disorders of sex development (DSD) with mild external genital abnormalities may be diagnosed after puberty. Here, we report a case of 46,XY complete gonadal dysgenesis with a novel missense variant in sex-determining region Y (SRY), diagnosed after primary amenorrhea. A 15-yr-old patient presented to our gynecology department with a chief complaint of amenorrhea. The patient was diagnosed with a 46,XY karyotype, and SRY gene positivity. Gonadotropin levels were high, whereas testosterone levels were low. A pelvic magnetic resonance imaging (MRI) revealed a hypoplastic uterus; however, no gonads could be identified. Laparoscopy revealed bilateral streak gonads, fallopian tube-like structures, and the uterus. The gonads were removed based on the risk of gonadal malignancy. Comprehensive genetic analysis of DSD revealed a previously unreported SRY variant, c.271A>T, p.Ser91Cys, and in silico analysis predicted the variant to be pathogenic. The patient was diagnosed with 46,XY complete gonadal dysgenesis with a novel missense variant in SRY. The patient continued female hormone replacement therapy and experienced breast enlargement and cyclic menstruation. Determining the etiology of DSD can be difficult, causing anxiety in patients and their families. In addition to surgical scrutiny, genetic analysis is important to aid in diagnosis and reassure patients and their families.

Abstract
In mammals, sex-determining region Y (SRY) gene plays vital role as a transcription factor to regulate the expression of the genes contributing to development of male genitals. Any mutation disrupting expression of SRY gene can cause disorders of sex development (DSDs). In this study, the examination of a hermaphroditic (female-like) Shal sheep which was referred for infertility is described. Initially, the reproductive system of the sheep was histologically and anatomically assessed. Karyotyping was used to determine the real gender of the animal. Sex hormones including progesterone, estradiol, and testosterone were measured by enzyme-linked immunosorbent assay (ELISA). Eventually, promoter part and SRY gene were sequenced and aligned to detect any potential mutation using NCBI data base. Although anatomical inspection led to identification of uterus, ovary, and enlarged clitoris as well as testes in the sheep, the karyotyping results interestingly revealed that the animal was genetically a male. Although the sheep had both male and female gonads, there were no overt signs of reproductive behavior and gamete production was not observed. Plasma steroid hormone levels were reported to be at basal levels. Additionally, a mutation was detected on the promoter of the SRY gene. In conclusion, the case implies that mutation on the promoter part of SRY gene could disrupt sexual development of the fetus culminating in DSDs in the sheep.

Abstract
The 2006 Chicago consensus statement of management of disorders/difference of sex development (DSD) has achieved advantages in clinical care and diagnosis for patients and families affect by DSD. This article provides a brief overview of contexts of care for physicians, and points out specific challenges in clinical practice that have arisen from the transformations of the sex/gender system in recent years. We focus on the impact of diagnosis and laboratory measurements. Both laboratory measurements and hormonal therapies still depend on the binary system. One problem is the lack of reference intervals for the different forms of DSD, which means that diversity is often neglected. In the following, we will give a brief insight into this complex topic.

Abstract
OBJECTIVE To outline our experimental gonadal tissue cryopreservation (GTC) protocol that does not disrupt the standard of care in medically-indicated gonadectomy for patients with differences of sex development, including highlighting the multidisciplinary collaborative protocol for when neoplasm is discovered in these cases. METHODS Two patients with complete gonadal dysgenesis who were undergoing medically-indicated prophylactic bilateral gonadectomy elected to pursue GTC. Both were found to have germ cell neoplasia in situ on initial pathologic analysis, requiring recall of the gonadal tissue, which had been cryopreserved. RESULTS Cryopreserved gonadal tissue was successfully thawed and transferred to pathology for complete analysis. No germ cells were identified in either patient nor were found to have malignancy, so further treatment beyond gonadectomy was not indicated. Pathologic information was communicated to each family, including that long-term GTC was no longer possible. CONCLUSION Organizational planning and coordination between the clinical care teams, GTC laboratory, and pathology were key to handling these cases with neoplasia. Processes that anticipated the possibility of discovering neoplasia within tissue sent to pathology and the potential need to recall GTC tissue to complete staging included (1) documenting the orientation and anatomical position of tissue processed for GTC, (2) defining parameters in which tissue will be recalled, (3) efficiently thawing and transferring GTC tissue to pathology, and (4) coordinating release of pathology results with verbal communication from the clinician to provide context. GTC is desired by many families and at the time of gonadectomy and is (1) feasible for patients with DSD, and (2) did not inhibit patient care in 2 patients with GCNIS.

Abstract
Disorders of sexual development (DSD) are associated with atypical chromosomal, gonadal, or phenotypic sex. It is likely that the number of cases of DSD are underestimated in the equine population. Monorchidism in the horse is very rare. This case report describes the clinical assessment of a phenotypic mare with stallion-like behavior which led to the diagnosis of a DSD. A 4-year-old Quarter Horse mare presented in good body condition, with normal external genitalia for a mare, and normal mammary glands with two bilaterally symmetric teats. No uterus, cervix, or gonads were detected on transrectal palpation. Transrectal ultrasonography revealed a single gonad in the right dorsal abdomen with the morphologic appearance of a testicle. Presurgical hormonal evaluation revealed elevated serum testosterone and anti-Müllerian hormone (AMH) concentrations. The right gonad was successfully removed via standing exploratory laparoscopy and submitted for histopathology. No gonad was identified on the left side during laparoscopy. Histopathologic examination confirmed that the excised gonad was a testicle. Cytogenetic and molecular analysis revealed a 64,XY, SRY-positive chromosomal constitution. Hormonal evaluation 5 weeks after surgery revealed low serum testosterone and AMH levels. A diagnosis of monorchidism was based on ultrasound examination, laparoscopic exploration of the abdomen, removal of a single gonad, and a subsequent decrease in serum testosterone and AMH concentrations to basal levels. In summary, a combination of clinical signs, endocrine evaluation, chromosomal and molecular analysis, and histopathology can be used in the diagnosis of DSD conditions.

Abstract
BACKGROUND Cytogenomic methods have gained space in the clinical investigation of patients with disorders/differences in sexual development (DSD). Here we evaluated the role of the SNP array in achieving a molecular diagnosis in Brazilian patients with syndromic DSD of unknown etiology. METHODS Twenty-two patients with DSD and syndromic features were included in the study and underwent SNP-array analysis. RESULTS In two patients, the diagnosis of 46,XX SRY + DSD was established. Additionally, two deletions were revealed (3q29 and Xp22.33), justifying the syndromic phenotype in these patients. Two pathogenic CNVs, a 10q25.3-q26.2 and a 13q33.1 deletion encompassing the FGFR2 and the EFNB2 gene, were associated with genital atypia and syndromic characteristics in two patients with 46,XY DSD. In a third 46,XY DSD patient, we identified a duplication in the 14q11.2-q12 region of 6.5 Mb associated with a deletion in the 21p11.2-q21.3 region of 12.7 Mb. In a 46,XY DSD patient with delayed neuropsychomotor development and congenital cataracts, a 12 Kb deletion on chromosome 10 was found, partially clarifying the syndromic phenotype, but not the genital atypia. CONCLUSIONS The SNP array is a useful tool for DSD patients, identifying the molecular etiology in 40% (2/5) of patients with 46,XX DSD and 17.6% (3/17) of patients with 46,XY DSD.

Ovarian germ cell tumors (OGCTs) are rare in adults; indeed, they occur predominantly in children, adolescents, and young adults, and they account for approximately 11% of cancer diagnoses in these groups. Because OGCTs are rare tumors, our current understanding of them is sparse; this is because few studies have investigated the molecular basis of pediatric and adult cancers. Here, we review the etiopathogenesis of OGCTs in children and adults, and we address the molecular landscape of these tumors, including integrated genomic analysis, microRNAs, DNA methylation, the molecular implications of treatment resistance, and the development of in vitro and in vivo models. An elucidation of potential molecular alterations may provide a novel field for understanding the pathogenesis, tumorigenesis, diagnostic markers, and genetic peculiarity of the rarity and complexity of OGCTs.

Mol Cytogenet 2023; 16:7. [PMID: 37202823 DOI: 10.1186/s13039-023-00639-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 05/07/2023] [Indexed: 05/20/2023] Open
Abstract
BACKGROUND X/Y translocations are highly heterogeneity in terms of clinical genetic effects, and most patients lack complete pedigree analysis for clinical and genetic characterization. RESULTS This study comprehensively analyzed the clinical and genetic characteristics of three new patients with X/Y translocations. Furthermore, cases with X/Y translocations reported in the literature and studies exploring the clinical genetic effects in patients with X/Y translocations were reviewed. All three female patients were carriers of X/Y translocations with different phenotypes. The karyotype for patient 1 was 46,X,der(X)t(X;Y)(p22.33;q12)mat, patient 2 was 46,X,der(X)t(X;Y)(q21.2;q11.2)dn, and patient 3 was 46,X,der(X)t(X;Y)(q28;q11.223)t(Y;Y)(q12;q11.223)mat. C-banding analysis of all three patients revealed a large heterochromatin region in the terminal region of the X chromosome. All patients underwent chromosomal microarray analysis, which revealed the precise copy number loss or gain. Data on 128 patients with X/Y translocations were retrieved from 81 studies; the phenotype of these patients was related to the breakpoint of the chromosome, size of the deleted region, and their sex. We reclassified the X/Y translocations into new types based on the breakpoints of the X and Y chromosomes. CONCLUSION X/Y translocations have substantial phenotypic diversity, and the genetic classification standards are not unified. With the development of molecular cytogenetics, it is necessary to combine multiple genetic methods to obtain an accurate and reasonable classification. Thus, clarifying their genetic causes and effects promptly will help in genetic counseling, prenatal diagnosis, preimplantation genetic testing, and improvement in clinical treatment strategies.

Abstract
Diagnosis and management of individuals who have differences of sex development (DSD) due to numerical or structural variations of sex chromosomes (NSVSC) remains challenging. Girls who have Turner syndrome (45X) may present with varying phenotypic features, from classical/severe to minor, and some remain undiagnosed. Boys and girls who have 45,X/46,XY chromosomal mosaicism may have Turner syndrome-like features and short stature; therefore, unexplained short stature during childhood requires karyotype analysis in both sexes, particularly if characteristic features or atypical genitalia are present. Many individuals with Klinefelter syndrome (47XXY) remain undiagnosed or are only diagnosed as adults due to fertility problems. Newborn screening by heel prick tests could potentially identify sex chromosome variations but would have ethical and financial implications, and in-depth cost-benefit analyses are needed before nationwide screening can be introduced. Most individuals who have NSVSC have lifelong co-morbidities and healthcare should be holistic, personalized and centralized, with a focus on information, psychosocial support and shared decision-making. Fertility potential should be assessed individually and discussed at an appropriate age. Oocyte or ovarian tissue cryopreservation is possible in some women who have Turner syndrome and live births have been reported following assisted reproductive technology (ART). Testicular sperm cell extraction (TESE) is possible in some men who have 45,X/46,XY mosaicism, but there is no established protocol and no reported fathering of children. Some men with Klinefelter syndrome can now father a child following TESE and ART, with multiple reports of healthy live births. Children who have NSVSC, their parents and DSD team members need to address possibilities and ethical questions relating to potential fertility preservation, with guidelines and international studies still needed.

Abstract
Key clinical message 5-Alpha reductase deficiency is an important cause of 46, XY disorder of sex development. Timely diagnosis and proper management by a multidisciplinary team can lead to a favorable outcome. Sex assignment should be deferred until puberty because spontaneous virilization occurs and the patient can engage in the decision-making process. Abstract 5-Alpha reductase deficiency is a genetic disorder causing 46, XY disorder of sex development (DSD). Typical clinical feature is a male with ambiguous genitalia or undervirilization at birth. Here we report three cases of this disorder within a family.

Abstract
Androgen insensitivity syndrome (AIS) is a rare genetic disorder that affects the development of the male reproductive system in individuals with a 46,XY karyotype. In addition to physical impacts, patients with AIS may face psychological distress and social challenges related to gender identity and acceptance. The major molecular etiology of AIS results from hormone resistance caused by mutations in the X-linked androgen receptor (AR) gene. Depending on the severity of androgen resistance, the wide spectrum of AIS can be divided into complete AIS (CAIS), partial AIS (PAIS), or mild AIS (MAIS). Open issues in the treatment and management of AIS include decisions about reconstructive surgery, genetic counseling, gender assignment, timing of gonadectomy, fertility and physiological outcomes. Although new genomic approaches have improved understanding of the molecular causes of AIS, identification of individuals with AIS can be challenging, and molecular genetic diagnosis is often not achievable. The relationship between AIS genotype and phenotype is not well established. Therefore, the optimal management remains uncertain. The objective of this review is to outline the recent progress and promote understanding of AIS related to the clinical manifestation, molecular genetics and expert multidisciplinary approach, with an emphasis on genetic etiology.

Abstract
BACKGROUND Disturbances in gonadal development lead to increased risk of gonadal malignancy in some but not all patients with differences in sex development (DSD). However, the natural history of these tumors is poorly described, and the literature remains sparse. OBJECTIVE The objective of this study was to describe the incidence of germ cell neoplasia in situ (GCNIS) and germ cell tumor (GCT) in a contemporary cohort of patients with DSD undergoing surgery and to provide long-term oncologic outcomes for these patients. STUDY DESIGN Patients with DSD who have undergone gonadectomy or gonadal biopsy were identified at four institutions. Clinical characteristics, pathology, and treatment details were obtained retrospectively. Patients were stratified into risk categories based on DSD diagnosis. Oncologic treatment and outcomes were recorded. Descriptive statistics are reported using parametric methods. RESULTS 83 patients were identified. Distribution of diagnoses is summarized in the summary table. 14 (16.9%) patients underwent gonadal biopsy, and 71 (85.5%) patients underwent gonadectomy (50/71 gonadectomies were bilateral). 8/83 (9.6%) patients had GCNIS or GCT (7 GCNIS, 1 GCT). Median age at surgery was 2.95 years (y) (interquartile range [IQR] 0.6-12.2) and 14y (IQR 0.85-16.9) in patients without and with GCNIS/GCT, respectively. All 8 patients with GCNIS/GCT had high or intermediate risk DSD diagnoses (4 mixed gonadal dysgenesis, 3 Turner with Y, 1 partial gonadal dysgenesis). Of the patients with high-risk diagnoses, 8/54 (15%) had GCNIS/GCT. No patient received adjuvant therapy, no patient had a recurrence, and all patients were living with mean follow up 6.4y. DISCUSSION The risk of gonadal malignancy is heterogeneous in the DSD population and can vary based on DSD diagnosis as well as maturation, testicularization, and location of the gonads. The most recent consensus recommendations on gonadal management emphasize risk stratification and consideration of gonadal surveillance based on gender of rearing, but supporting literature remains sparse. In this contemporary cohort of DSD patients who underwent gonadal surgery, most patients did not have evidence of adverse pathology, all patients with malignant or premalignant pathology had a high/intermediate risk DSD diagnosis, and all patients with GCNIS/GCT were treated with surgery alone without recurrence. CONCLUSIONS The distribution of patients with premalignant and malignant gonadal pathology and DSD in this cohort aligns with prior literature, and oncologic outcomes were excellent. These data add valuable information to the current literature and highlight the necessity to develop appropriate screening regimens for retained gonads.

Abstract
In recent years, an increasing number of abnormal DNA genotypes caused by chromosomal abnormalities have been revealed in cases of individual identification and sex-typing analysis, especially analyses of the amelogenin and short tandem repeat (STR) loci on the sex chromosomes. Here, we report a 17-year-old female with Turner syndrome typed as male due to the presence of the amelogenin Y allele. The Y-STR haplotype showed allele dropout of three Y-STR loci (DYS549, DYS392 and DYS448). Further examination showed that the proband's karyotype was 45,X/46,X,del(Y) (q11.23), and the deletion of the Yp11.2 region was confirmed to encompass the observed microdeletion of the azoospermia factor (AZF)b + c region. One challenge in forensics is inaccurate sex typing of individuals at the molecular level, particularly for individuals with chromosomal abnormalities. This case suggests that various medical evaluations, including the examination of sex-related manifestations, karyotypes, and clinical phenotypes of individuals, along with the detection of sex-typing gene markers will be beneficial to overcome the issues caused by cytogenetic disorders of the sex chromosomes.

Abstract
The 46,XY disorder of sexual development (DSD) is a rare congenital condition characterized by a 46,XY karyotype associated with complete or disturbed female gonadal development and a non-virilized phenotype. The presence of Y chromosome material in these patients' karyotypes increases the risk of germ cell tumor development. The present study reports a unique case of a 16-year-old phenotypically female patient presenting with primary amenorrhea, who was later diagnosed with 46,XY DSD. After bilateral salpingo-oophorectomy, the patient was diagnosed with stage IIIC dysgerminoma. The patient received four cycles of chemotherapy and showed a good response. The patient is currently alive and well, with no evidence of disease after the residual lymph node resection.

Abstract
Differences of sex development (DSDs) are a group of congenital conditions characterized by a discrepancy between chromosomal, gonadal, and genital sex development of an individual, with significant impact on medical, psychological and reproductive life. The genetic heterogeneity of DSDs complicates the diagnosis and almost half of the patients remains undiagnosed. In this context, chromosomal imbalances in syndromic DSD patients may help to identify new genes implicated in DSDs. In this study, we aimed at describing the burden of chromosomal imbalances including submicroscopic ones (copy number variants or CNVs) in a cohort of prenatal syndromic DSD patients, and review their role in DSDs. Our patients carried at least one pathogenic or likely pathogenic chromosomal imbalance/CNV or low-level mosaicism for aneuploidy. Almost half of the cases resulted from an unbalanced chromosomal rearrangement. Chromosome 9p/q, 4p/q, 3q and 11q anomalies were more frequently observed. Review of the literature confirmed the causative role of CNVs in DSDs, either in disruption of known DSD-causing genes (SOX9, NR0B1, NR5A1, AR, ATRX, …) or as a tool to suspect new genes in DSDs (HOXD cluster, ADCY2, EMX2, CAMK1D, …). Recurrent CNVs of regulatory elements without coding sequence content (i.e. duplications/deletions upstream of SOX3 or SOX9) confirm detection of CNVs as a mean to explore our non-coding genome. Thus, CNV detection remains a powerful tool to explore undiagnosed DSDs, either through routine techniques or through emerging technologies such as long-read whole genome sequencing or optical genome mapping.
