Delivering the Diagnosis of Sex Chromosome Aneuploidy: Experiences and Preferences of Parents and Individuals

Enhancing intersex healthcare: A qualitative study of parental perspectives on the role of genetics

Intersex individuals, encompassing people with diverse sex characteristics that do not fit binary frameworks of sex, have long faced a history of medical secrecy, discrimination, and societal stigma, contributing to their limited social visibility. In recent years, increased awareness of intersex issues and a robust advocacy movement have drawn significant attention to the experiences of intersex individuals and their families. This study contributes to the existing literature by examining the experiences and needs of parents of intersex individuals within genetic healthcare systems, bridging a critical gap, and advocating for more comprehensive and supportive healthcare practices. Semi-structured interviews were conducted with 14 parents of intersex individuals, and reflexive thematic analysis was used to inductively generate four major themes. Themes highlighted the need for improved accessibility of intersex healthcare, the importance of multidisciplinary healthcare teams, and the significance of clinical diagnosis provided by genetics professionals. Furthermore, the study highlighted the necessity of a thoughtful approach to information provision and the impact of genetic investigations on family dynamics. Genetics professionals can play a pivotal role in raising awareness about intersex variations, improving diagnostic processes, collaborating within healthcare teams, and providing specialized support to address psychosocial concerns. The study underscores the importance of treating families as a collective entity and addressing the impact of genetic investigations on the family unit. By addressing the challenges and implementing the recommendations outlined, healthcare institutions can create a more compassionate, inclusive, and effective healthcare environment for the intersex community.

Parental questions about sex chromosome aneuploidies regarding sex, gender, and sexual orientation as reported by genetic counselors in a prenatal setting

The introduction of cell-free DNA screening has resulted in increased prenatal identification of sex chromosome aneuploidies (SCAs). This study aimed to evaluate genetic counselor experiences disclosing SCAs positive prenatal screening or testing results and genetic counselor-reported parental questions regarding sex, gender, and sexual orientation. Forty-eight prenatal genetic counselors completed the survey. When asked to quantify their experiences, 97.9% of counselors reported disclosing a SCAs positive screen result within the previous year, and 81.3% disclosed a diagnostic result. Of those counselors, 53.8% reported always or often receiving parental questions about sex, 33% always or often about gender, and 25% always or often regarding sexual orientation. Counselors were asked to share examples of parental questions following a positive screen or diagnostic testing for SCAs. Parental questions were stratified by karyotype and content analysis revealed questions about the fetus' sex, anatomy, reproduction, being cisgender, gender expression, behavior, being transgender, and sexual orientation. The examples of parental questions provided by genetic counselors suggested some parents may have misconceptions about the intersection of SCAs with sex, gender, and sexual orientation following prenatal screening or diagnostic testing. The majority of counselors (83.3%) agreed to some extent that they desired further education on responding to parental questions about SCAs. Findings from this research suggest a need for genetic counseling strategies that accurately and respectfully discuss SCAs in the context of sex, gender, and sexual orientation with prenatal patients.

Policy and laboratory practice: How quality control procedures for genetic testing perpetuate biological essentialism and discrimination against transgender, gender diverse, and intersex people

Transgender, gender diverse, and intersex (TGDI) individuals face significant health disparities due to individual and systemic experiences of discrimination, impacting their access to healthcare. While clinical genetic testing has become increasingly accessible to the general population, the field of clinical genetics perpetuates a narrative of biological essentialism, which creates barriers for TGDI patients. Biological essentialism upholds that sex is a binary, fixed, and innate characteristic, a misconception that has been historically weaponized against the TGDI community in both individual experiences of discrimination and anti-trans legislation, among other systemic forms of oppression. Rejecting this discriminatory framework requires careful consideration of, and changes to, long-established practices that often go unquestioned, such as quality control metrics in genetic testing, in order to improve TGDI patients' outcomes and access to genetic services. The sex-check, comparing an individuals reported sex against their sex chromosomes, is an example of how laboratory genetics practices reinforce the narrative that sex is determined purely by chromosomal composition. Additionally, the sex-check "outs" TGDI people in clinical settings, creating a discriminatory and unsafe environment for these patients. Alternative quality control procedures and inclusive practices, such as clearer delineation of sex and gender on test requisition forms, are proposed to improve TGDI patient experiences. Genetic counselors and other clinical providers have a responsibility to address historical discrimination and advocate for changes to laboratory practice, so as to create affirming experiences for TGDI patients.

Exploring preferences and support needs for disclosing 47, XXY status: A qualitative study of adults with XXY

There are minimal guidelines regarding the disclosure of XXY, otherwise called Klinefelter syndrome, in healthcare or within the family. The increased use of cell-free DNA (cfDNA) to screen for fetal aneuploidy and sex chromosomes bolsters the importance of providing genetic counselors, other healthcare professionals (HCPs), and parents with XXY-led disclosure information. The aim of this qualitative study was to discern the preferences of adults of XXY in the disclosure of XXY status across the lifespan to best inform the clinical and social aspects of their care. Fifteen semi-structured interviews were conducted with adults with XXY to gain their perspective on healthcare and support needs, the impact their care has had on their perception and acceptance of XXY, as well as their disclosure preferences across age groups. Interviews were coded and analyzed using reflexive thematic analysis through a social constructivist lens, from which four themes were generated: (1) lack of support within the healthcare system affects quality of care; (2) stigma and shame impacts XXY individuals' decisions to disclose information to others; (3) communication of XXY genetic results to children should be thoughtful and age-appropriate; and (4) attention to psychosocial needs is integral to comprehensive care. Novel findings of this study, which include the detrimental impacts of negative disclosure experiences on relationships with HCPs and self-identity, underscore specific clinical and social support needs for individuals with XXY. This study highlights the need for specialized support across one's lifespan, particularly within interdisciplinary clinics staffed by HCPs knowledgeable about the overall health of individuals with XXY. Participants stress the importance of empathetic delivery of XXY status and discussions on sex and gender to mitigate shame and stigma. Advocating for ongoing support services, including referrals to specialists and mental health resources, participants also endorse a personalized approach to childhood disclosure by parents, or in collaboration with HCPs, aiming to preserve trust, empower the child, and consider their maturity level. This study emphasizes the importance of providing tailored support to individuals with XXY, prioritizing informed decision-making, emotional well-being, and holistic care.

Toward depathologizing queerness: An analysis of queer oppression in clinical genetics

Critically examining the way that the field of clinical genetics has impacted queer communities offers the field an opportunity to strengthen our commitment to inclusive high-quality care to all patients, families, and communities. This article reviews the origins of clinical genetics and genetic counseling in the eugenics movement and how this ontology promoted harmful medical practices grounded in assumptions of what is "normal." We critically examine existing clinical genetics practices and how commonly used binary frameworks for gender, sex, and sexuality perpetuate heteronormative, cisnormative, and bioessentialist assumptions. In order to move toward queer inclusivity, the genetic counseling field must first take accountability for past injustices. Restorative justice and trauma-informed approaches offer a way to engage with the queer community and to begin to rectify the history of medical harm. Through our analysis, we advocate for expanding efforts to depathologize queerness, promote bodily autonomy, and provide equitable healthcare for the queer community.

Navigating the disclosure landscape: Parents' perspectives on healthcare professionals' role in supporting intersex children and families

Intersex, an umbrella term, describes individuals with sex characteristics that cannot be exclusively categorized into binary definitions of male or female. The intersex community faces a lack of social visibility perpetuated by a history of medical discrimination and pathologization shaped by "normalizing" genital surgeries without the child's consent. Despite efforts to reform clinical practice, there remains a paucity of research centering the needs of the intersex community and their families. This study explored parents' perspectives on how healthcare professionals (HCPs), such as genetics professionals, can provide patient-centered education and support when parents first learn of their child's intersex variation, with the aim of offering recommendations to HCPs to promote parental adjustment and protect intersex children's right to autonomy. Thirteen qualitative semi-structured interviews were conducted with 14 parents of intersex children. Through reflexive thematic analysis, under the framework of an agency-based approach to intersex health, thematic categories were inductively conceptualized, including barriers and facilitators to HCPs' sensitivity and to parental adjustment in the early disclosure environment. Barriers to HCPs' sensitivity were imposed by educational, religious, or medical institutions, along with sociocultural prejudices and pathologizing language. Barriers to parental adaptation included uncertainty regarding their child's future, sociocultural gender norms, and unsuitable information provision. Incorporating parental needs in the disclosure environment can facilitate familial acceptance, including normalization of variations of sex characteristics (VSCs), enhanced medical education, facilitation of patients' navigation, and prioritization of parents' social support needs.

Reaction to Diagnosis and Parental Concerns in Parents of Children and Young Adults With XYY Syndrome

BACKGROUND

There is a growing interest in exploring parents' views on the benefits of early diagnosis and awareness of sex chromosome trisomies. However, only a few studies focus specifically on the experience of parents of children with XYY syndrome. The present study aimed to assess, in parents of individuals with XYY, the perceived severity of their children's condition, their level of satisfaction with the disclosure process and their concerns about their children's present and future condition.

METHODS

A national online sample of 56 Italian parents of children and young adults diagnosed with XYY syndrome participated in the study. They filled out a specifically developed online survey that assessed their children's areas of concern, their experience with the disclosure process and their worries about their children's condition.

RESULTS

Seventy per cent of the parents received a prenatal diagnosis, whereas 30% received a postnatal diagnosis. High individual variability was found in the parent report of their child's condition. The most frequent areas of concern were attention regulation, emotion control and behaviour control. Individuals with a postnatal diagnosis showed more severe profiles. Parents were generally dissatisfied with the disclosure process, with no differences between prenatal and postnatal disclosure. However, more than 50% of the parents who received a prenatal disclosure reported that their child's condition was less severe than they had expected. In contrast, only 11% of the parents with postnatal disclosure reported this situation. Parents' concerns were negatively related to global satisfaction with the disclosure process and the correspondence between current and expected conditions but positively associated with the child's severity level.

CONCLUSIONS

The results suggest that clear and realistic information during the disclosure process to parents is needed in both prenatal and postnatal communication and may alleviate parents' concerns.

Towards equity & inclusion: a critical examination of genetic Counselling Education on Intersex Healthcare

BACKGROUND

Intersex describes a diversity of individuals with variations in sex characteristics (VSC), reflecting underlying differences in reproductive anatomy, hormones, and/or genes and chromosomes. With a shift towards socially-conscious clinical practices, genetic counsellors (GCs) are increasingly needing to provide comprehensive care to individuals with VSC and their families. However, the current quality of training provided to genetic counsellors on intersex health is unclear.

METHODS

Qualitative interviews were conducted between Jan-Feb 2021 with 20 current and graduated students of Canadian GC training programs to assess the quality of GC education on intersex health topics. An agency-based model of VSC health as proposed by Crocetti et al. was used to guide the inductive thematic data analysis.

RESULTS

Results revealed three key themes: limited discussions on psychosocial considerations when caring for intersex individuals, enthusiasm for integrating more intersex training into the curriculum, and personal initiative in ensuring equity and justice in the care of individuals with VSC.

CONCLUSIONS

These findings demonstrate existing knowledge gaps in the GC curriculum, with a need to increase the profession's overall awareness on intersex issues. GC training programs have an opportunity to meet the desires of students while promoting person-centered and validating healthcare for the intersex community.

The emotional journey of adapting to prenatally identified trisomy X

There is a paucity of research on the experiences of parents of children with trisomy X (47,XXX). Increased prenatal diagnoses associated with advances in noninvasive prenatal screening necessitate a better understanding of how trisomy X impacts family systems. This qualitative investigation aimed to describe the lived experience of parents of young daughters with prenatally identified trisomy X to guide genetic counseling. Semi-structured qualitative interviews were conducted via teleconferencing with parents (n = 11) of girls with trisomy X, ages 6-44 months. A descriptive phenomenological approach was used to code transcripts for significant statements and reduce data into themes describing the experience of receiving a diagnosis of trisomy X and the experience of early parenting in this population. Participants described an emotional journey of adapting to prenatally identified trisomy X. Four descriptive themes included two related, yet distinct, life stages: Negative Diagnostic Experience and a Hopeful Early Childhood, as well as two ongoing experiences: Persistent Ambiguity and Coping with and Adapting to Uncertainty. Results suggest providers should carefully consider word choice and timing in delivery of diagnosis, and genetic counseling should provide expectant parents with current research specific to trisomy X, facilitate connections with other parents of young girls with trisomy X, introduce developmental monitoring approaches, and be prepared to support families with a range of emotional responses to the diagnosis and decisions regarding disclosure.

Clinical practice guidelines for the care of girls and women with Turner syndrome

Turner syndrome (TS) affects 50 per 100 000 females. TS affects multiple organs through all stages of life, necessitating multidisciplinary care. This guideline extends previous ones and includes important new advances, within diagnostics and genetics, estrogen treatment, fertility, co-morbidities, and neurocognition and neuropsychology. Exploratory meetings were held in 2021 in Europe and United States culminating with a consensus meeting in Aarhus, Denmark in June 2023. Prior to this, eight groups addressed important areas in TS care: (1) diagnosis and genetics, (2) growth, (3) puberty and estrogen treatment, (4) cardiovascular health, (5) transition, (6) fertility assessment, monitoring, and counselling, (7) health surveillance for comorbidities throughout the lifespan, and (8) neurocognition and its implications for mental health and well-being. Each group produced proposals for the present guidelines, which were meticulously discussed by the entire group. Four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with systematic review of the literature. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with members from the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology, the European Reference Network on Rare Endocrine Conditions, the Society for Endocrinology, and the European Society of Cardiology, Japanese Society for Pediatric Endocrinology, Australia and New Zealand Society for Pediatric Endocrinology and Diabetes, Latin American Society for Pediatric Endocrinology, Arab Society for Pediatric Endocrinology and Diabetes, and the Asia Pacific Pediatric Endocrine Society. Advocacy groups appointed representatives for pre-meeting discussions and the consensus meeting.

Evidence-based recommendations for delivering the diagnosis of X & Y chromosome multisomies in children, adolescents, and young adults: an integrative review

BACKGROUND

The diagnosis of supernumerary X & Y chromosome variations has increased following the implementation of genetic testing in pediatric practice. Empirical evidence suggests that the delivery of the diagnosis has a lasting impact on how affected individuals and their parents perceive and adapt to the diagnosis. The purpose of this review is to synthesize the literature to obtain useful recommendations for delivering a pediatric diagnosis of a sex chromosome multisomy (SCM) based upon a growing body of quantitative and qualitative literature on patient experiences.

METHODS

We conducted an integrative literature review using PubMed, Web of Science and CINAHL employing keywords "genetic diagnosis delivery," "genetic diagnosis disclosure," "sex chromosome aneuploidy," "Klinefelter syndrome" or ""47, XXY," "Jacob syndrome" or "47, XYY," "Trisomy X," "Triple X" or "47, XXX," and "48 XXYY from January 1, 2000, to October 31, 2023.

RESULTS

Literature supports that patients and parents value the provision of up-to-date information and connection with supportive resources. Discussion of next steps of care, including relevant referrals, prevents perceptions of provider abandonment and commitment to ongoing support. Proactively addressing special concerns such as disclosing the diagnosis to their child, family, and community is also beneficial. Tables are provided for useful information resources, medical specialties that may be required to support patients, and common misconceptions that interfere with accurate information about the diagnosis.

CONCLUSION

Patient experiences suggest there should be heightened attention to diagnosis delivery, in reference to the broader ethical and social impacts of a SCM diagnosis. We present recommendations for optimal disclosure of a SCM diagnosis in early and late childhood, adolescence, and young adulthood.

Healthcare and support experiences of adolescents and young adults diagnosed with 47,XXY, 47,XXX, and 48,XXYY

Sex chromosome aneuploidies (SCAs) are among the most common chromosomal conditions. There is little scholarship on how adolescents and young adults (AYAs) affected by SCA engage with and adapt to their diagnosis. In order to understand how AYAs adapt to a SCA diagnosis, we conducted a secondary analysis of qualitative interviews with AYAs. Eight in-depth semi-structured interviews with individuals with a diagnosis of 47,XXY, 47,XXX, and 48,XXYY were analyzed for iterative themes related to adaptation to a SCA diagnosis in accordance with standard qualitative methodology. Our findings suggest that the process of adaptation is highly variable and complex and is mediated by external factors including diagnosis delivery and community support. Factors associated with adaptation include feeling understood and supported by healthcare providers; researching the condition; receiving hormone replacement therapy; and receiving support from a community of peers. As access to prenatal and pediatric genetic testing continues to expand, non-genetic pediatric providers are increasingly likely to interact with individuals with SCAs as part of their initial diagnostic odyssey or ongoing medical management. Understanding the diversity of lived experiences of AYAs with SCAs is helpful for healthcare providers to facilitate holistic care and provide meaningful support to patients.

The burden of disease for children born alive with Turner syndrome-A European cohort study

BACKGROUND

Turner syndrome is a rare congenital anomaly caused by complete or partial X chromosome monosomy that may affect mortality and morbidity in childhood.

METHODS

This population-based data-linkage cohort study, as part of the EUROlinkCAT project, investigated mortality and morbidity for the first 5 years of life for liveborn European children diagnosed with Turner syndrome. Thirteen population-based registries in 10 countries from the European surveillance of congenital anomalies (EUROCAT) network participated. Data on children born 1995-2014 and diagnosed with Turner syndrome were linked to mortality, hospital and prescription records. Children with any congenital anomaly and children without a congenital anomaly were included for comparison on morbidity.

RESULTS

Out of a population of 5.8 million livebirths 404 were diagnosed with Turner syndrome prenatally or in infancy and 95.5% survived to their fifth birthday. During the first year of life 72.3% (95% CI 59.5;81.6) of children with Turner syndrome were hospitalized, the median length of stay was 5.6 days (95% CI 3.5;7.7) and 18.7% (95% CI 13.9;23.9) underwent surgery. After the first year of life hospitalizations and length of stay decreased but more children underwent surgery (30.8% [95% CI 17.6;44.7]). In the first 5 years the percentage of children with Turner syndrome having a prescription for antibiotics was 12%-20% per year and increased with the age of child.

CONCLUSIONS

In the first year of life, the burden of disease was relatively high for children with Turner syndrome. The outlook is more positive beyond the first year, though overall morbidity still exceeded that of children without congenital anomalies.

Differences of sexual development: genetic counseling considerations in the prenatal setting

PURPOSE OF REVIEW

With the rapid adoption of noninvasive prenatal screening (NIPS), predictive fetal sex information is available early in pregnancy. This information can conflict with the results of other prenatal tests such as fetal ultrasound or diagnostic testing and raise the possibility of a fetal difference of sexual development (DSD). In this review, we describe recent studies examining the counseling and outcomes of prenatally suspected DSD.

RECENT FINDINGS

Discordance in prenatal genetic testing results can cause confusion and anxiety in families as expectations of testing are not often discussed in detail prior to testing. There are no established guidelines for the counseling or management of such situations.

SUMMARY

We present case vignettes to highlight relevant counseling points and considerations to aid in the development of guidelines and best practices in the management of DSD in the prenatal setting.

Ethical issues associated with prenatal screening using non-invasive prenatal testing for sex chromosome aneuploidy

Prenatal screening for sex chromosome aneuploidies (SCAs) is increasingly available through expanded non-invasive prenatal testing (NIPT). NIPT for SCAs raises complex ethical issues for clinical providers, prospective parents and future children. This paper discusses the ethical issues that arise around NIPT for SCAs and current guidelines and protocols for management. The first section outlines current practice and the limitations of NIPT for SCAs. It then outlines key guidelines before discussing the ethical issues raised by this use of NIPT. We conclude that while screening for SCAs should be made available for people seeking to use NIPT, its implementation requires careful consideration of what, when and how information is provided to users.

Experiences of receiving an increased chance of sex chromosome aneuploidy result from non-invasive prenatal testing in Australia: "A more complicated scenario than what I had ever realized"

Many non-invasive prenatal testing (NIPT) platforms screen for sex chromosome aneuploidy (SCA) and SCA analysis is generally included in Australia where NIPT is available as a self-funded test. Little is known about the experience of receiving an NIPT result indicating an increased chance of SCA. This study aimed to explore the experiences of people who received this result and their perspectives on the information, care, and support they received from healthcare practitioners (HCPs). Semi-structured interviews were conducted with people who received an NIPT result indicating an increased chance of SCA and continued their pregnancy. Most participants only had contact with a genetic counselor after receiving their result. Transcribed data were analyzed using rigorous thematic analysis to identify important patterns and themes. Participants (18 women, 2 male partners) described embarking on NIPT, primarily based on advice from their HCP and without much consideration. Consequently, participants expressed feeling unprepared for the unanticipated complexity of their NIPT result and were faced with making a time-sensitive decision about a condition they had not previously considered. While more pre-test information was desired, timely access to genetic counseling post-test assisted with adjustment to the result. These findings suggest that routinization of NIPT may be compromising informed decision-making, resulting in unpreparedness for an increased chance result. Given the increasing uptake and expanding scope of NIPT, resources should be dedicated to educating HCPs offering NIPT and ensuring timely access to genetic counseling post-result. With appropriate funding, genetics services may be able to play a central role in offering information and support to both people who undertake NIPT and their HCPs ordering the testing. Implementing a publicly funded screening program in Australia could assist with standardizing prenatal screening care pathways and consequently better access to appropriate resources.

Understanding the phenotypic spectrum and family experiences of XYY syndrome: Important considerations for genetic counseling

XYY syndrome is characterized by a variable neurodevelopmental phenotype, with features including developmental delays, cognitive impairments, and an increased risk for mental health conditions. There are two recent developments that have primarily motivated this review. The first is the increased use of non-invasive prenatal screening (NIPS), which will likely result in more individuals being diagnosed with XYY prenatally. As such, health care providers (HCPs) both within genetics and outside of the specialty are more likely to encounter this diagnosis in the future. The second is advances in the understanding of the phenotypic variability of XYY through biobank and deep phenotyping efforts. As the phenotypic spectrum of XYY syndrome continues to expand, families will face greater uncertainty when receiving this diagnosis. Given both of these developments, HCPs will need to have up-to-date and accurate information about XYY to better counsel families. Furthermore, the ability to employ effective counseling techniques, such as anticipatory guidance, will aid in supporting and guiding families through the diagnostic journey. This review aims to provide insight on the neurodevelopmental and psychosocial aspects of XYY syndrome by discussing current research and borrowing from the relevant psychosocial literature of other genetic conditions. In this way, we hope to equip HCPs with the ultimate goal of improving the care and support provided to individuals with XYY and their families.

Prenatal Detection and Evaluation of Differences of Sex Development: A Qualitative Interview Study of Parental Perspectives and Unmet Needs

Objectives

Prenatal diagnoses of differences of sex development (DSD) are increasing due to availability of cell‐free DNA screening (cell‐free DNA screening (cfDNA)). This study explores first‐hand experiences of parents whose children had prenatal findings of DSD.

Methods

Eligible parents were identified through chart review at a pediatric center and interviewed about their prenatal evaluation, decision making, informational sources, and support systems. Interviews were coded using a combined inductive and deductive thematic analysis. Parents also completed quantitative measures of decisional regret.

Results

Seventeen parents (13 mothers; 4 fathers) of 13 children (with 7 DSD diagnoses) were recruited. Four children had discordance between sex predicted by cfDNA versus prenatal ultrasound, and 2 had non‐binary appearing (atypical) genitalia on prenatal ultrasound. Of these 6, 3 were not offered additional prenatal testing or counseling.

Most parents described tension between obtaining support through disclosure of their child's diagnosis and preserving their child's autonomy/privacy, highlighting the need for mental health support.

Conclusion

This is the first study to gather qualitative data from parents whose children had prenatal findings of DSD. We identified multiple targets for intervention to improve care for patients with DSD across the lifespan, including improvements in clinician education, pre‐ and post‐test counseling, and patient education materials.

What's already known about this topic? What does this study add?

Prenatal detection of potential differences of sex development (DSD) is increasing as the availability of non‐invasive prenatal screening increases.

Algorithms have been developed for the diagnostic evaluation, but little is known about the psychosocial implications of that process.

This study focuses on the first‐hand experiences of families whose children had prenatal findings of a potential DSD, to identify existing sources of support and information, and areas for future improvement.

Population-based Assessment of Cardiometabolic-related Diagnoses in Youth With Klinefelter Syndrome: A PEDSnet Study

CONTEXT

Diabetes and cardiovascular diseases are common among men with Klinefelter syndrome (KS) and contribute to high morbidity and mortality.

OBJECTIVE

To determine if cardiometabolic-related diagnoses are more prevalent among youth with KS than matched controls in a large population-based cohort.

METHODS

Secondary data analysis of electronic health records from 6 pediatric institutions in the United States (PEDSnet). Patients included all youth with KS in the database (n = 1080) and 4497 youth without KS matched for sex, age (mean 13 years at last encounter), year of birth, race, ethnicity, insurance, site, and duration of care (mean 7 years). The main outcome measures were prevalence of 5 cardiometabolic-related outcomes: overweight/obesity, dyslipidemia, dysglycemia, hypertension, and liver dysfunction.

RESULTS

The odds of overweight/obesity (OR 1.6; 95% CI 1.4-1.8), dyslipidemia (3.0; 2.2-3.9), and liver dysfunction (2.0; 1.6-2.5) were all higher in KS than in controls. Adjusting for covariates (obesity, testosterone treatment, and antipsychotic use) attenuated the effect of KS on these outcomes; however, boys with KS still had 45% greater odds of overweight/obesity (95% CI 1.2-1.7) and 70% greater odds of liver dysfunction (95% CI 1.3-2.2) than controls, and both dyslipidemia (1.6; 1.1-2.4) and dysglycemia (1.8; 1.1-3.2) were higher in KS but of borderline statistical significance when accounting for multiple comparisons. The odds of hypertension were not different between groups.

CONCLUSION

This large, population-based cohort of youth with KS had a higher odds of most cardiometabolic-related diagnoses than matched controls.

'I Wish the School Had a Better Understanding of the Diagnosis': parent perspectives on educational needs of students with sex chromosome aneuploidies

Students with sex chromosome aneuploidies (SCAs) are at increased risk for learning disabilities and often require individualized supports in the school setting. Parents of students with rare disorders such as SCAs possess a unique understanding of their child's educational experiences and play a crucial role in the development of successful school support plans. This international survey study aimed to inductively capture parent perspectives on educational needs and supports for students with SCAs. Parents of youth with SCAs ages 5-21 years (n = 305) provided free-text responses to open-ended questions about their child's education. Qualitative content analysis using a bioecological systems framework resulted in three overarching themes. Overall, parents identified multiple factors related to the SCA diagnosis that act as barriers to learning, a strong need for school-based social and emotional supports, and elusive or incomplete educational support plans. Based on these findings, we recommend developing robust family-school partnerships, increased collaboration between the school and the child's medical team, and acknowledgement of the significant role the genetic condition plays in the educational experiences of students with SCAs. Specific suggestions for school support plans for students with SCAs are explored, such as providing school-based behavioral health supports and explicit teaching of executive function strategies.

Prenatal Genetic Testing for Intersex Conditions in Canada

Intersex individuals face human rights violations, discrimination, and stigmatization worldwide. Diagnosis in infants is uncommon, with between 1 in 2000 and 1 in 4500 infants born with ambiguous external genitalia sufficient to warrant genetic and endocrine studies. However, estimates of the actual proportion of the population falling under the broader umbrella of intersex, including sexual variation at the chromosomal, gonadal, hormonal, or genital level, are as high as 1.7%. As the rise of non-invasive prenatal screening (NIPS) capable of identifying intersex conditions at the fetal stage has increased the potential for prenatal detection, there is an urgent need for attention to the potential ethical challenges that may arise from earlier and more frequent detection. There has been growing attention in recent years to the harms faced by intersex individuals at the hands of the medical community. In the prenatal context, genetic counseling is one avenue by which prospective parents might be helped to understand the full spectrum of intersexuality and form realistic expectations for their children. However, best practices and medical policies to prevent stigmatization and discrimination against intersex individuals remain underdeveloped. There is presently a lack of Canadian-specific guidance or explicit legal protections for intersex individuals to guide health care providers in their relationship with these patients and their families. In this commentary, we argue that this gap calls for increased training for health care providers that incorporates the voices and concerns of the intersex community.

The Expert in the Room: Parental Advocacy for Children with Sex Chromosome Aneuploidies

OBJECTIVE

Owing to fragmentation in the medical system, many parents of children with disabilities report taking on a care coordinator and advocate role. The parental advocacy and care coordination requirements are further amplified in this population because of a lack of awareness about sex chromosome aneuploidies (SCAs) in medical and social services settings, as well as the complex needs of affected children. This burden disproportionately affects mothers and low-resource families as a result of gendered ideas of parenthood and social stratification in resource access. The aim of this study is to understand the unique parental burdens of SCAs and family support needs.

METHODS

We conducted 43 interviews with individuals with SCAs and/or their parents and qualitatively coded and analyzed the transcripts for themes relating to parent advocacy, medical services, social and educational services, and coping.

RESULTS

Our findings indicate that parents must repeatedly advocate for their concerns about their child to be taken seriously before diagnosis and continue to advocate for services and interventions throughout childhood and adolescence. Parents also report the need to educate health care professionals about their child's medical condition. A majority of the parent participants were women, and single mothers reported high levels of emotional burden.

CONCLUSION

Parents of children with SCAs shoulder additional roles of medical advocate and care coordinator. This causes excessive burden on families but also disadvantages families in which parents are unable to act as an advocate for their child.

Prenatal Genetic Diagnosis of a Sex Chromosome Aneuploidy: Parent Experiences

Sex chromosome aneuploidies (SCAs) occur in 1 in every 400 births. SCAs are highly variable and have uncertain prognoses, complicating the delivery of prenatal cell-free DNA (cfDNA) results or diagnosis following amniocentesis or chorionic villus sampling. Using a mixed-methods approach, we explored the experiences of parents receiving a prenatal diagnosis of a fetus with SCA. Responses to open-ended questions were qualitatively analyzed. Of the 323 parents who completed the survey, 122 received a prenatal diagnosis and answered at least one open-ended question. Most parents did not recall being informed that cfDNA screening or amniocentesis could reveal the presence of a SCA prior to testing and described feeling unprepared for a positive result. Variation was found between parents who were delivered a diagnosis by a genetic professional versus other clinical specialties. Many parents expressed that the diagnosis was delivered in a way that emphasized the negative attributes of the SCA and that they were provided limited support materials. Parents who received a prenatal diagnosis of a SCA expressed a desire for more supportive delivery of prenatal diagnosis that focuses on parental education and nuanced discussion of potential phenotypes. Genetic counselors should be aware of the range of parental experiences when receiving a SCA diagnosis from non-genetic providers. Prenatal SCA diagnoses are predicted to increase as prenatal cfDNA screening becomes more widely used. Collaborations for greater provider education and comprehensive materials on SCAs are essential to facilitate the delivery of SCA diagnoses and improve parent understanding and support.

Family experiences and attitudes about receiving the diagnosis of sex chromosome aneuploidy in a child

The most common sex chromosome aneuploidies (SCA) (47, XXY; 47, XYY; 47, XXX) frequently result in a milder phenotype than autosomal aneuploidies. Nevertheless, these conditions are highly variable and more symptomatic phenotypes may require significant clinical involvement, including specialty care. While historically most individuals with mild phenotypes remained undiagnosed during their lifetime, the increasing use of genetic testing in clinical care has increased the prenatal and postnatal diagnosis of SCAs. These genetic tests are frequently ordered by nongenetic providers who are also responsible for delivering the diagnosis. We surveyed parents of children (n = 308) to evaluate their experience of receiving a diagnosis and their support needs. The majority (73.3%) received the diagnosis from a nongenetic medical provider. Following a prenatal diagnosis parents reported experiencing depression, anxiety, and less optimism than those receiving a postnatal diagnosis. Few parents reported receiving materials explaining their child's condition that they found to be up-to-date, accurate, and unbiased. The frequently negative reported experiences of parents at time of diagnosis suggests more educational opportunities should be provided for nongenetic providers in order to become more informed about these conditions and communicate the diagnosis in a way parents experience as supportive.
