Abstract
Disorders of sex development (DSD) is a broad term for congenital conditions with a discrepancy in chromosomal, gonadal, or anatomic sex. Pediatricians are often faced with the challenge of managing a newborn/infant with atypical genitalia or an older child with disordered puberty, which come under the purview of DSD. This article provides an update for pediatricians on comprehensive approach to DSD with a focus on atypical genitalia.

Abstract
Background Differences of sex development (DSD) are congenital conditions linked to atypical development of chromosomal, gonadal, or anatomical sex. Objective The aim of this study was to demonstrate our experiences at the Diabetes Endocrine and Metabolism Pediatric Unit (DEMPU), Faculty of Medicine, Cairo University in the field of DSD by focusing on the clinical presentation, laboratory profile, classification, and etiological diagnosis of these conditions. In addition, the present study intended to delineate the importance of serum anti-Müllerian hormone (AMH) and inhibin B in detecting the presence of functioning testicular tissue. Methods This cohort study included 451 infants and children with various clinical presentations of DSD. The study performed a retrospective analysis on medical records of established DSD cases to evaluate the clinical importance of AMH and inhibin B. In addition, newly diagnosed patients were prospectively analyzed. Results Three hundred thirty-six (74.5%) patients were 46,XY DSD, 98 (21.7%) were 46,XX DSD, 14 patients had other karyotypes and 3 had missing karyotypes. Among the 46XY DSD patients, the most common cause was partial androgen insensitivity. In contrast, congenital adrenal hyperplasia constituted the most common diagnosis in 46,XX DSD cases. The cut off value of serum AMH was 14.5 ng/ml with 100% sensitivity and 55.1% specificity. Conclusion Partial androgen insensitivity was the most important cause of 46,XY DSD in Egyptian children, and congenital adrenal hyperplasia was the most common cause of 46,XX DSD. AMH was valuable in detecting functioning testicular tissue.

A New MAMLD1 Variant in an Infant With Microphallus and Hypospadias With Hormonal Pattern Suggesting Partial Hypogonadotropic Hypogonadism-Case Report. Front Endocrinol (Lausanne) 2022; 13:884107. [PMID: 35837313 PMCID: PMC9274080 DOI: 10.3389/fendo.2022.884107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Accepted: 05/17/2022] [Indexed: 11/13/2022] Open
Abstract
MAMLD1 (X chromosome) is one of the recognized genes related to different sex development. It is expressed in testis and ovaries and seems to be involved in fetal sex development and in adult reproductive function, including testosterone biosynthesis. However, its exact role remains unclear. Over 40 genetic variants have been described, mainly in male individuals and mostly associated with hypospadias. Although MAMLD1 has been shown to regulate the expression of the steroidogenic pathway, patients with MAMLD1 variants mostly show normal gonadal function and normal testosterone levels. Here we describe a patient (46,XY) with hypospadias and microphallus, with low testosterone and dihydrotestosterone (DHT) levels, and with inappropriately low values of luteinizing hormone (LH) during minipuberty. This hormonal pattern was suggestive of partial hypogonadotropic hypogonadism. A stimulation test with hCG (4 months) showed no significant increase in both testosterone and dihydrotestosterone concentrations. At 5 months of age, he was treated with intramuscular testosterone, and the penis length increased to 3.5 cm. The treatment was stopped at 6 months of age. Our gonadal function massive-sequencing panel detected a previously unreported nonsense variant in the MAMLD1 gene (c.1738C>T:p.Gln580Ter), which was classified as pathogenic. This MAMLD1 variant, predicting a truncated protein, could explain his genital phenotype. His hormonal profile (low testosterone, dihydrotestosterone, and LH concentrations) together with no significant increase of testosterone and DHT plasma concentrations (hCG test) highlight the potential role of this gene in the biosynthesis of testosterone during the fetal stage and minipuberty of the infant. Besides this, the LH values may suggest an involvement of MAMLD1 in the LH axis or a possible oligogenesis. It is the first time that a decrease in DHT has been described in a patient with an abnormal MAMLD1.

Intersexuality/Differences of Sex Development through the Discourse of Intersex People, Their Relatives, and Health Experts: A Descriptive Qualitative Study. Healthcare (Basel) 2022; 10:671. [PMID: 35455848 PMCID: PMC9032209 DOI: 10.3390/healthcare10040671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 03/16/2022] [Accepted: 03/31/2022] [Indexed: 11/24/2022] Open
Abstract
Intersex/differences of sex development (DSD) conditions are divergences among genitalia, gonads, and chromosome patterns. These variances have been present for millennia and socially defined according to the cultural system established. The aim of this study is to describe the perspectives of adult intersex/DSD people, their relatives, and intersex/DSD expert professionals in Spain. A descriptive qualitative study design was adopted. The study was carried out in several locations in Spain. Individual in-depth interviews were conducted and addressed to 12 participants (4 intersex/DSD people, 3 relatives, and 5 professional experts). A total of 4 spheres, 10 categories, and 26 subcategories were obtained. The number of verbatims obtained in each of the spheres described were intersex/DSD as a community (n = 54), health sphere approach (n = 77), law sphere approach (n = 12), and psychosocial approach (n = 73). Regarding intersex/DSD as a community sphere, there is a clear need of promoting education on sex and body diversity. With respect to the health sphere, it is mentioned the inadequacy of services and how this has a negative impact on the health of intersex/DSD people. Regarding the law sphere, it is highlighted the need of designing legislations at a national level which protect and defend the rights of intersex/DSD people. Regarding the psychosocial sphere, these people suffer from social isolation, secrecy, shame, self-identity questioning, and mental disorders that negatively impact their quality of life.

Copy Number Variations in Genetic Diagnosis of Congenital Adrenal Hyperplasia Children. Front Genet 2022; 13:785570. [PMID: 35309130 PMCID: PMC8924405 DOI: 10.3389/fgene.2022.785570] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 01/31/2022] [Indexed: 11/24/2022] Open
Abstract
Background: Congenital adrenal hyperplasia (CAH) is a monogenic disorder caused by genetic diversity in the CYP21A2 gene, with 21-hydroxylase deficiency (21-OHD) as the most common type. Early sex assignment and early diagnosis of different genetic variations with a proper technique are important to reduce mortality and morbidity. Proper early sex identification reduces emotional, social, and psychological stress. Aim: Detection of a spectrum of aberrations in the CYP21A2 gene, including copy number variations, gene conversion, chimeric genes, and point variations. Methods: The CYP21A2 gene was screened using MLPA assay in 112 unrelated Egyptian children with 21-OHD CAH (33 males and 79 females). Results: In the studied group, 79.5% were diagnosed within the first month of life. 46.8% of the genetic females were misdiagnosed as males. Among the copy number variation results, large deletions in 15.4% and three types of chimeric genes in 9% (CH-1, CH-7, and CAH-X CH-1) were detected. Regarding gene dosage, one copy of CYP21A2 was found in 5 cases (4.5%), three copies were detected in 7 cases (6.3%), and one case (0.9%) showed four copies. Eight common genetic variants were identified, I2G, large deletions, large gene conversion (LGC), I172N, F306 + T, -113 SNP, 8bp Del, and exon 6 cluster (V237E and M239K) with an allelic frequency of 32.62%, 15.45%, 7.30%, 3.00%, 2.58%, 2.15%, 0.86%, and 0.86%, respectively. Conclusion: High prevalence of copy number variations highlights the added value of using MLPA in routine laboratory diagnosis of CAH patients.

Abstract
A young adult patient with 46XX congenital adrenal hyperplasia (CAH) presented with recurrent painful haematuria. CAH was diagnosed at birth following ambiguous genitalia. Hormonal treatment was started, female gender was assigned and feminising genitoplasty was planned, however the patient was lost to follow-up. Gender dysphoria started to occur during childhood which prompted the family to raise the patient as a boy. He eventually identified himself as a male. Examination revealed a male phenotype with severely virilised genitalia. Imaging studies confirmed the presence of uterus with low confluent urogenital sinus. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed, and the troublesome symptoms were cured.

Abstract
OBJECTIVE Gender assignment in infants and children with disorders of sex development (DSD) is a stressful situation for both patient/families and medical professionals. METHODS The purpose of this study was to investigate the results of gender assignment recommendations in children with DSD in our clinic from 1999 through 2019. RESULTS The mean age of the 226 patients with DSD at the time of first admission were 3.05±4.70 years. 50.9% of patients were 46,XY DSD, 42.9% were 46,XX DSD and 6.2% were sex chromosome DSD. Congenital adrenal hyperplasia (majority of patients had 21-hydroxylase deficiency) was the most common etiological cause of 46,XX DSD. In 46,XX patients, 87 of 99 (89.7%) were recommended to be supported as a female, 6 as a male, and 4 were followed up. In 46,XY patients, 40 of 115 (34.8%) were recommended to be supported as a female, and 70 as male (60.9%), and 5 were followed up. In sex chromosome DSD patients, 3 of 14 were recommended to be supported as a female, 9 as a male. The greatest difficulty in making gender assignment recommendations were in the 46,XY DSD group. CONCLUSION In DSD gender assignment recommendations, the etiologic diagnosis, psychiatric gender orientation, expectation of the family, phallus length and Prader stage were effective in the gender assignment in DSD cases, especially the first two criteria. It is important to share these experiences among the medical professionals who are routinely charged with this difficult task in multidisciplinary councils.

Abstract
A phalloplasty is a complex genital reconstruction procedure of creating a neophallus. Several techniques to create a neophallus are described, based on different vascularized flaps, and each of them has its advantages and drawbacks. The aim of this study is to present musculocutaneous latissimus dorsi (MLD) flap as a viable option for total phalloplasty, with an interest in clinical outcomes and complications. A comprehensive literature review of all available reports about MLD flap phalloplasty was made. The following keywords were used on PubMed: latissimus dorsi musculocutaneous/myocutaneous free flap and phalloplasty. Research criteria revealed five articles and the results of 182 patients were analyzed. A total number of the patients, indications, operative technique, follow-up period, postoperative results, and complications were presented. In conclusion, MLD free flap presents a good choice for phalloplasty providing sufficient amount of tissue for safe implantation of penile prosthesis and successful penetrative sexual intercourse. The erogenous sensitivity is preserved with clitoris or glans penis incorporated into the base of the neophallus, and voiding in a standing position is achievable after urethral reconstruction. The main drawback is the lack of tactile sensation of the neophallus and the significant advantage is a well-concealed donor site.

Abstract
Differences/disorders of sex development (DSD) are a heterogeneous group of congenital conditions that result in discordance between an individual's sex chromosomes, gonads, and/or anatomic sex. Advances in the clinical care of patients and families affected by 46,XY DSD have been achieved since publication of the original Consensus meeting in 2006. The aims of this paper are to review what is known about morbidity and mortality, diagnostic tools and timing, sex of rearing, endocrine and surgical treatment, fertility and sexual function, and quality of life in people with 46,XY DSD. The role for interdisciplinary health care teams, importance of establishing a molecular diagnosis, and need for research collaborations using patient registries to better understand long-term outcomes of specific medical and surgical interventions are acknowledged and accepted. Topics that require further study include prevalence and incidence, understanding morbidity and mortality as these relate to specific etiologies underlying 46,XY DSD, appropriate and optimal options for genitoplasty, long-term quality of life, sexual function, involvement with intimate partners, and optimizing fertility potential.
