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.”

What’s missing in sex chromosome aneuploidies? Representation and inclusion

Article Title: What’s missing in sex chromosome aneuploidies? Representation and inclusion

Authors: Mehmet, McDonald, Saldarriaga, Pineros-Leano, and Dwyer

Date of Publication: January 2022

“Given that KS/TS happen by chance, theoretically, these rates should be similar across racial/ethnic groups. Namely, the rates of KS/TS should be similar among non-Hispanic Whites and Black, Indigenous, People of Color (BIPOC) communities. Currently, it is unknown to what extent HR-QoL has been examined in BIPOC communities affected by KS/TS. To provide culturally-informed care for all patients with KS/TS, it is critical to understand the experiences of BIPOC communities. We conducted a systematic review of the literature on HR-QoL in KS/TS to examine the extent that BIPOC communities have been included and represented in the literature to date.”

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.”

Cardiometabolic-related Diagnoses in Youth With Klinefelter Syndrome

Article Title: Population-based Assessment of Cardiometabolic-related Diagnoses in Youth With Klinefelter Syndrome: A PEDSnet Study

Authors: Davis, Nokoff, Furniss, Pyle, Valentine, Fechner, Ikomi, Magnusen, Nahata, Vogiatzi, and Dempsey

Date of Publication: February 1, 2022

“Diabetes and cardiovascular diseases are common among men with Klinefelter syndrome (KS) and contribute to high morbidity and mortality.”

“This large, population-based cohort of youth with KS had a higher odds of most cardiometabolic-related diagnoses than matched controls.”

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.”

Delaying testicular sperm extraction in 47,XXY Klinefelter patients

Article Title: Delaying testicular sperm extraction in 47,XXY Klinefelter patients does not impair the sperm retrieval rate, and AMH levels are higher when TESE is positive

Date of Publication: September 16, 2022

“Should testicular sperm extraction (TESE) in non-mosaic 47,XXY Klinefelter syndrome (KS) patients be performed soon after puberty or could it be delayed until adulthood?”
