Eosinophilic esophagitis in individuals with sex chromosome aneuploidies: Clinical presentations and management implications

Article Title: Eosinophilic esophagitis in individuals with sex chromosome aneuploidies: Clinical presentations and management implications

Authors: Howell, Buchanan, Davis, Miyazawa, Furuta, Tartaglia, and Nguyen

Date of Publication: September 9, 2021

“The findings of this chart review demonstrate the importance for the community affected by SCA conditions to have an increased awareness of the variable presentations of eosinophilic esophagitis (including coping strategies), especially among different age groups and in the context of neurodevelopmental problems, the need for specific screening for EoE symptoms, and referral to GI for evaluation and treatment. Such clinical knowledge and action can facilitate diagnosing EoE as early as possible and improve quality of life, symptom management, and limit progression of severity for patients.”

Variegation of autism related traits across seven neurogenetic disorders

Article Title: Variegation of autism related traits across seven neurogenetic disorders

Authors: Lee, Niu, Zhang, Clasen, Kozel, Smith, Wallace, and Raznahan

Date of Publication: April 7, 2022

“Gene dosage disorders (GDDs) constitute a major class of genetic risks for psychopathology, but there is considerable debate regarding the extent to which different GDDs induce different psychopathology profiles. The current research speaks to this debate by compiling and analyzing dimensional measures of several autism-related traits (ARTs) across seven diverse GDDs.”

Recommendations to improve the patient experience and avoid bias when prenatal screening/testing

Article Title: Recommendations to improve the patient experience and avoid bias when prenatal screening/testing

Authors: Meredith, Brackett, Diaz, Freeman, Huggins, Khan, Leach, Levitz, Michie, Onufer, Skotko, Smith, White, Waller, and Ayers

Date of Publication: October 29, 2022

“While prenatal screening and testing have expanded substantially over the past decade and provide access to more genetic information, expectant parents are more likely to describe the diagnosis experience as negative than positive. In addition, the conversations that take place during these experiences sometimes reflect unconscious bias against people with disabilities. Consequently, an interdisciplinary committee of experts, including people with disabilities, family members, disability organization leaders, healthcare and genetics professionals, and bioethicists, reviewed selected published and gray literature comparing the current state of the administration of prenatal testing to the ideal state. Subsequently, the interdisciplinary team created recommendations for clinicians, public health agencies, medical organizations, federal agencies, and other stakeholders involved with administering prenatal screening and testing to create better patient experiences; conduct training for healthcare professionals; create, enforce, and fund policies and guidelines; and engage in more robust data collection and research efforts.”

Positive predictive value of noninvasive prenatal testing for sex chromosome abnormalities

Article Title: Positive predictive value of noninvasive prenatal testing for sex chromosome abnormalities

Authors: Guo, Cai, Lin, Xue, Huang, and Xu

Date of Publication: August 12, 2022

A clinic had 47,855 patients undergo NIPT (noninvasive prenatal testing). They found that the positive predictive value (PPV) for sex chromosome abnormalities was 36.9%. The PPV in patients aged 30–34 years was significantly higher than that in patients aged < 30 years.

Supporting students with sex chromosome aneuploidies in educational settings

Article Title: Supporting students with sex chromosome aneuploidies in educational settings: Results of a nationwide survey

Authors: Thompson, Davis, Janusz, Frith, Pylead, Howell, Boada, Wilson, and Tartaglia

Date of Publication: August 2022

“Many parents reported their children’s educators had little to no knowledge of SCA conditions, justifying a need to train teachers and policy makers in the unique educational needs of children and adolescents with SCAs. School psychologists should be aware of the frequent need for accommodations and individualized support plans in this population so they can support children and families by advocating for early and comprehensive evaluations and intervention plans.”

‘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.”

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.”

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.
