‘I Wish the School Had a Better Understanding of the Diagnosis’: parent perspectives on educational needs of students with SCAs

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

Authors: Thompson, Stinnett, Tartaglia, Davis, and Janusz

Date of Publication: March 13, 2022

“Students with SCAs, have a unique educational profile that may be challenging to support within the schools. Challenges with reading and writing, EF, fatigue/endurance, social skills and emotion management may act as barriers to learning, and are frequently triggered in busy classroom environments. Skills hovering in the borderline range are common to the SCA phenotype and are not often well served by special education systems with limited resources and strict cut-offs for qualification. As a result, families may feel they need to advocate strongly for their child to receive adequate support services. To improve the educational experience of children with SCAs, we recommend increased collaboration between the school and the child’s medical team, strong parent partnerships and acknowledgement of the significant role the genetic condition plays in the educational experiences of students with SCAs.”

Early Preventive Intervention for Young Children With Sex Chromosome Trisomies (XXX, XXY, XYY)

Article Title: Early Preventive Intervention for Young Children With Sex Chromosome Trisomies (XXX, XXY, XYY): Supporting Social Cognitive Development Using a Neurocognitive Training Program Targeting Facial Emotion Understanding

Authors: Bouw, Swaab, and van Rijn

Date of Publication: February 25, 2022

“The significant improvement in facial emotion recognition, with large effect sizes, suggests that there are opportunities for positively supporting the development of social cognition in children with an extra X- or Y-chromosome, already at a very young age. This evidence based support is of great importance given the need for preventive and early training programs in children with SCT, aimed to minimize neurodevelopmental impact.”

Early developmental impact of sex chromosome trisomies on ADHD symptomology in young children

Article Title: Early developmental impact of sex chromosome trisomies on attention deficit-hyperactivity disorder symptomology in young children

Authors: Kuiper, Swaab, Tartaglia, and van Rijn

Date of Publication: June 18, 2021

“Individuals with sex chromosome trisomies ([SCT], XXX, XXY, and XYY)) are at increased risk for neurodevelopmental problems, given that a significant portion of the sex chromosome genes impact brain functioning. An elevated risk for psychopathology has also been described, including attention deficit-hyperactivity disorder (ADHD). The present study aimed at identifying early markers of ADHD, providing the first investigation of ADHD symptomology in very young children with SCT.”

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.”

What microRNAs could tell us about the human X chromosome

Article Title: What microRNAs could tell us about the human X chromosome

Authors: Di Palo, Siniscalchi, Salerno, Russo, Gravholt and Potenza

Date of Publication: April 30, 2020

“MicroRNAs (miRNA) are small-non coding RNAs endowed with great regulatory power, thus playing key roles not only in almost all physiological pathways, but also in the pathogenesis of several diseases. Surprisingly, genomic distribution analysis revealed the highest density of miRNA sequences on the X chromosome; this evolutionary conserved mammalian feature equips females with a larger miRNA machinery than males. However, miRNAs contribution to some X-related conditions, properties or functions is still poorly explored. With the aim to support and focus research in the field, this review analyzes the literature and databases about X-linked miRNAs, trying to understand how miRNAs could contribute to emerging gender-biased functions and pathological mechanisms, such as immunity and cancer. A fine map of miRNA sequences on the X chromosome is reported, and their known functions are discussed; in addition, bioinformatics functional analyses of the whole X-linked miRNA targetome (predicted and validated) were performed. The emerging scenario points to different gaps in the knowledge that should be filled with future experimental investigations, also in terms of possible implications and pathological perspectives for X chromosome aneuploidy syndromes, such as Turner and Klinefelter syndromes.”

A review of neurocognitive functioning of children with sex chromosome trisomies

Article Title: A review of neurocognitive functioning of children with sex chromosome trisomies: Identifying targets for early intervention

Authors: Van Rijn, Urbanus, and Swaab

Date of Publication: July 2, 2019

“Results of the reviewed studies show that although traditionally, the focus has been on language and intelligence (IQ) in this population, recent studies suggest that executive functioning and social cognition may also be significantly affected already in childhood. These findings suggest that neuropsychological screening of children diagnosed with SCT should be extended, to also include executive functioning and social cognition. Knowledge about these neurocognitive risks is important to improve clinical care and help identify targets for early support and intervention programs to accommodate for the needs of individuals with SCT.”

The behavioral profile of children aged 1–5 years with sex chromosome trisomy

Article Title: The behavioral profile of children aged 1–5 years with sex chromosome trisomy (47,XXX, 47,XXY, 47,XYY)

Authors: Van Rijn, Tartaglia, Urbanus, Swaab, and Cordeiro

Date of Publication: May 20, 2020

“Collectively, these results demonstrate the importance of behavioral screening for behavioral problems in routine clinical care for children with SCT from a young age. Social–emotional problems may require special attention, as these problems seem most prominent, showing increased risk across the full age range, and with these problems occurring regardless of the timing of diagnosis, and across all three SCT karyotypes.”

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.

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.”
