Congenital heart defects associated with aneuploidy syndromes

Article Title: Congenital heart defects associated with aneuploidy syndromes: New insights into familiar associations

Authors: Lin, Santoro, High, Goldenberg, and Gutmark-Little

Date of Publication: November 7, 2019

“The frequent occurrence of congenital heart defects (CHDs) in chromosome abnormality syndromes is well-known, and among aneuploidy syndromes, distinctive patterns have been delineated. We update the type and frequency of CHDs in the aneuploidy syndromes involving trisomy 13, 18, 21, and 22, and in several sex chromosome abnormalities (Turner syndrome, trisomy X, Klinefelter syndrome, 47,XYY, and 48,XXYY).We also discuss the impact of noninvasive prenatal screening (mainly, cell-free DNA analysis), critical CHD screening, and the growth of parental advocacy on their surgical management and natural history. We encourage clinicians to view the cardiac diagnosis as a ‘phenotype’ which supplements the external dysmorphology examination. When detected prenatally, severe CHDs may influence decision-making, and postnatally, they are often the major determinants of survival. This review should be useful to geneticists, cardiologists, neonatologists, perinatal specialists, other pediatric specialists, and general pediatricians. As patients survive (and thrive) into adulthood, internists and related adult specialists will also need to be informed about their natural history and management.”

ACRC Accomplishments

In 2015, the AXYS Board of Directors voted to approve the development of the AXYS Clinical and Research Consortium (ACRC). The two goals that AXYS defined at that time were to improve the availability and the quality of services to the X&Y variation community. As the ACRC grew, the original goals were refined to be as follows:

  • Make life easier for those seeking evaluation and treatment.
  • Bring consistency to treatment that is consensus and/or evidence-based.
  • Advance the overall X&Y variation field through coordinated efforts including research.
  • Bring clinical excellence to the field of X&Y variations.

Though each clinic operates independently, as members of a consortium, they collaborate with one another, share informational resources, and have the opportunity to participate in joint research projects.

In addition, AXYS organizes annual meetings of the consortium at which members meet to discuss topics important to the X&Y chromosome variation community. AXYS works to ensure that all families impacted by any of the chromosome variations have access to the best available evaluation and treatment or treatment recommendations.

Timeline of the ACRC

The Expert in the Room

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

Authors: Richardson, Riggan, and Allyse

Date of Publication: November 2, 2020

“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.”

Counseling in Pediatric Populations at Risk for Infertility and/or Sexual Function Concerns

Article Title: Counseling in Pediatric Populations at Risk for Infertility and/or Sexual Function Concerns

Authors: Nahata, Quinn, and Tishelman

Date of Publication: July 30, 2018

“Health care providers and parents report challenges in knowing how and when to discuss these issues. In this context, the goal of this clinical report is to review evidence and considerations for providers related to information sharing about impaired fertility and sexual function in pediatric patients attributable to congenital and acquired conditions or treatments.”

Sex differences in psychiatric disorders: what we can learn from sex chromosome aneuploidies

Article Title: Sex differences in psychiatric disorders: what we can learn from sex chromosome aneuploidies

Authors: Green, Flash, and Reiss

Date of Publication: January 2019

“The study of individuals with sex chromosome aneuploidies provides a promising framework for studying sexual dimorphism in neurodevelopmental and psychiatric disorders. Here we will review and contrast four syndromes caused by variation in the number of sex chromosomes: Turner syndrome, Klinefelter syndrome, XYY syndrome, and XXX syndrome. Overall we describe an increased rate of attention deficit hyperactivity disorder and autism spectrum disorder, along with the increased rates of major depressive disorder and anxiety disorders in one or more of these conditions. In addition to contributing unique insights about sexual dimorphism in neuropsychiatric disorders, awareness of the increased risk of neurodevelopmental and psychiatric disorders in sex chromosome aneuploidies can inform appropriate management of these common genetic disorders.”

Changes in the cohort composition of TS, severe non-diagnosis of KS, 47,XXX and 47,XYY syndrome

Article Title: Changes in the cohort composition of Turner syndrome and severe non-diagnosis of Klinefelter, 47,XXX and 47,XYY syndrome: a nationwide cohort study

Authors: Claus H. Gravholt, MD, PhD et al

Date of Publication: January 14, 2019

“The prevalence of TS is higher than previously identified, and the karyotypic composition of the TS population is changing. Non-diagnosis is extensive among KS, Triple X and Double Y, whereas all TS seem to become diagnosed. The diagnostic activity has increased among TS with other karyotypes than 45,X as well as among KS and Double Y.”
