Sex chromosome aneuploidies and fertility: 47,XXY, 47,XYY, 47,XXX and 45,X/47,XXX

Article title: Sex chromosome aneuploidies and fertility: 47,XXY, 47,XYY, 47,XXX and 45,X/47,XXX

Author: Alan D. Rogol

Date of Publication: August 1, 2023

“Assisted reproductive technology, especially micro-testicular sperm extraction, has an important role, especially for those with 47,XXY; however, more recent data show promising techniques for the in vitro maturation of spermatogonial stem cells and 3D organoids in culture. Assisted reproductive technology is more complex for the female, but vitrification of oocytes has shown promising advances.”

The emotional journey of adapting to prenatally identified trisomy X

Article Title: The emotional journey of adapting to prenatally identified trisomy X

Authors: Thompson, Tisher, Davis, Miller, Kirk, Tartaglia, and Howell

Date of Publication: August 19, 2023

“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.”

Sex Chromosome Dosage Effects on White Matter

Article Title: Sex Chromosome Dosage Effects on White Matter

Authors: Warling, Yavi, Clasen, Blumenthal, Lalonde, Raznahan, and Liu

Date of Publication: June 12, 2021

“These findings represent the most complete maps of X- and Y-chromosome effects on human white matter to date, and show how such changes connect to psychopathological symptoms and gray matter anatomy.”

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.”

Association of Supernumerary Sex Chromosome Aneuploidies With Venous Thromboembolism

Article Title: Association of Supernumerary Sex Chromosome Aneuploidies With Venous Thromboembolism

Authors: Berry, Finucane, Myers, Abril, Kirchner, Ledbetter, Martin, and Oetjens

Date of Publication: January 17, 2023

“Adults with supernumerary sex chromosome aneuploidies compared with 2 sex chromosomes had a small but statistically significant increased risk of VTE. Further research is needed to understand the clinical implications of this association.”

Associations of psychiatric disorders with sex chromosome aneuploidies in the Danish iPSYCH2015 dataset: a case-cohort study

Article Title: Associations of psychiatric disorders with sex chromosome aneuploidies in the Danish iPSYCH2015 dataset: a case-cohort study

Authors: Sánchez, Montalbano, Vaez, Krebs, Byberg-Grauholm, Mortensen, Børglum, Hougaard, Nordentoft, Geschwind, Buil, Schork, Thompson, Raznahan, Helenius, Werge, and Ingason

Date of Publication: February 2023

“Increased risks of psychiatric disorders associated with sex chromosome aneuploidies, combined with low rates of clinical diagnosis of sex chromosome aneuploidies, compromise the adequate provision of necessary health care and counselling to affected individuals and their families, which might be helped by increased application of genetic testing in clinical settings.”

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.”

Patterns of psychopathology and cognition in sex chromosome aneuploidy

Article Title: Patterns of psychopathology and cognition in sex chromosome aneuploidy

Authors: Rau, Whitman, Schauder, Gogate, Lee, Kenworthy, and Raznahan

Date of Publication: December 15, 2021

“There is domain-specific variation in psychopathology across SCA groups and domain-specific correlation between psychopathology and IQ within SCAs. These findings (i) help to tailor clinical assessment of this common and impactful family of genetic disorders and (ii) suggest that dosage abnormalities of X- and Y-linked genes impart somewhat distinct profiles of neuropsychiatric risk.”

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.”

Triple X syndrome: Psychiatric disorders and impaired social functioning as a risk factor

Article Title: Triple X syndrome: Psychiatric disorders and impaired social functioning as a risk factor

Authors: Otter, Campforts, Stumpel, Van Amelsvoort, and Drukker

Date of Publication: December 21, 2022

“This study aims to describe the prevalence of psychiatric disorders in adults with TXS in a relatively large and less biased group of participants.”

“Women with TXS are vulnerable to developing psychiatric disorders, and women with both TXS and impaired social functioning are even more vulnerable.”
