Evidence-based recommendations for delivering the diagnosis of X&Y chromosome multisomies

Article Title: Evidence-based recommendations for delivering the diagnosis of X&Y chromosome multisomies in children, adolescents, and young adults: an integrative review

Authors: Riggan, Ormond, Allyse, and Close

Date of Publication: April 22, 2024

“Patient experiences suggest there should be heightened attention to diagnosis delivery, in reference to the broader ethical and social impacts of a SCM diagnosis. We present recommendations for optimal disclosure of a SCM diagnosis in early and late childhood, adolescence, and young adulthood.”

Executive Dysfunction in Klinefelter Syndrome: Associations With Brain Activation and Testicular Failure

Article Title: Executive Dysfunction in Klinefelter Syndrome: Associations With Brain Activation and Testicular Failure

Authors: Foland-Ross, Ghasemi, Lozano Wun, Aye, Kowal, Ross, and Reiss

Date of Publication: August 18, 2023

“These findings indicate a neural basis for executive dysfunction in KS and suggest alterations in pubertal development may contribute to increased severity of this cognitive weakness. Future studies that examine whether these patterns change with testosterone replacement therapy are warranted.”

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.”

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.”

Quality of life in men with Klinefelter Syndrome – a multicentre study

Article Title: Quality of life in men with Klinefelter Syndrome – a multicentre study

Authors: Franik, Fleischer, Kortmann, Stikkelbroek, D’Hauwers, Bouvattier, Slowikowska-Hilczer, Grunenwald, Van de Grift, Cartault, Richter-Unruh, Reisch, Thyen, IntHout, and Claahsen-van der Grinten

Date of Publication: August 14, 2023

“Overall QOL in European men with KS is significantly worse compared to a healthy European reference population. Especially the presence of discrimination, less social activities and chronic health problems is associated with lower physical, psychological and social QOL. Further studies are necessary to investigate if a multidisciplinary approach may help to provide adequate counseling and psycho-social support to improve quality of life.”

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.”

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.”
