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.”

Supernumerary sex chromosome abnormalities – new developments and future trajectories

Article Title: Supernumerary sex chromosome abnormalities – new developments and future trajectories – A summary of the 2022 3rd International Workshop on Klinefelter syndrome, XYY and Trisomy X

Authors: Gravholt, Ferlin, Gromoll, Juul, Raznahan, Van Rijn, Rogol, Skakkebæk, Tartaglia, and Swaab

Date of Publication: January 4, 2023

“The 3rd International Workshop on Klinefelter Syndrome, Trisomy X, and 47,XYY syndrome was held in Leiden, the Netherlands, on September 12-14, 2022. Here, we review new data presented at the workshop and discuss scientific and clinical trajectories. We focus on shortcomings in knowledge and therefore point out future areas for research.”

Early impact of X- and Y-chromosome variations on social communication and social emotional development in 1–2-year-old children

Article Title: Early impact of X- and Y-chromosome variations (XXX, XXY, XYY) on social communication and social emotional development in 1–2-year-old children

Authors: Bouw, Swaab, Tartaglia, Jansen, and Van Rijn

Date of Publication: February 18, 2022

“These findings suggest that SCT [sex chromosome trisomies] impact the maturation of the social brain already from an early age, and stress the importance of early monitoring and (preventive) support early social development in young children with SCT.”

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.

Noninvasive prenatal screening (NIPS) results for participants of the eXtraordinarY babies study

Article Title: Noninvasive prenatal screening (NIPS) results for participants of the eXtraordinarY babies study: Screening, counseling, diagnosis, and discordance

Authors: Howell, Davis, Thompson, Brown, Tanda, Kowal, Alston, Ross, and Tartaglia

Date of Publication: September 6, 2022

“The majority (57%) of parents with a NIPS result positive for SCA defer diagnostic confirmation until birth; however, diagnostic results can be discordant with NIPS results, which may impact genetic counseling.”

Ovarian reserve evaluation in a woman with 45,X/47,XXX mosaicism: A case report and a review of literature

Article Title: Ovarian reserve evaluation in a woman with 45,X/47,XXX mosaicism: A case report and a review of literature

Authors: Tang, Lin, Guo, Hou, and Yu

Date of Publication: April 22, 2019

FISH should be recommended to evaluate low proportion mosaicism in similar cases. Due to the risk of ovarian failure, fertility preservation for patients with 45,X/47,XXX mosaicism at a younger age must be considered.”

Early symptoms of autism spectrum disorder in children with sex chromosome trisomies

Article Title: Early symptoms of autism spectrum disorder (ASD) in 1–8 year old children with sex chromosome trisomies (XXX, XXY, XYY), and the predictive value of joint attention

Authors: Bouw, Swaab, Tartaglia, Wilson, van der Velde, and van Rijn

Date of Publication: September 15, 2022

“These findings show a neurodevelopmental impact of the extra X or Y chromosome on social adaptive development associated with risk for ASD already from early childhood onward. These findings advocate for close monitoring and early (preventive) support, aimed to optimize social development of young children with SCT.”
