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.”

Clinical, Cognitive and Neurodevelopmental Profile in Tetrasomies and Pentasomies: A Systematic Review

Article Title: Clinical, Cognitive and Neurodevelopmental Profile in Tetrasomies and Pentasomies: A Systematic Review

Authors: Ricciardi, Cammisa, Bove, Picchiotti, Spaziani, Isidori, Aceti, Giacchetti, Romani, and Sogos

Date of Publication: November 9, 2022

“Our study aimed to analyse the neurocognitive, linguistic and behavioural profile of patients affected by supernumerary SCAs, specifically tetrasomy and pentasomy. We investigated the verbal abilities, both expressive and receptive, as well as the metalinguistic comprehension and attentive skills
of these patients.”

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.”

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.”

Understanding the phenotypic spectrum and family experiences of XYY syndrome: Important considerations for genetic counseling

Article Title: Understanding the phenotypic spectrum and family experiences of XYY syndrome: Important considerations for genetic counseling

Authors: Jodarski, Duncan, Torres, Gore, Raznahan, and Similuk

Date of Publication: January 7, 2023

“XYY syndrome is a diagnosis that has significant implications on not only the affected individual, but the family as well. It is therefore imperative that HCPs fully understand the range of lived experiences with XYY so that we can better counsel and care for affected individuals and their families.”

Deep phenotypic analysis of psychiatric features in genetically defined cohorts: application to XYY syndrome

Article Title: Deep phenotypic analysis of psychiatric features in genetically defined cohorts: application to XYY syndrome

Authors: Raznahan, Rau, Schaffer, Liu, Fish, Mankiw, Xenophontos, Clasen, Joseph, Thurm, Blumenthal, Bassett, and Torres

Date of Publication: February 20, 2023

“Across the full XYY group, we find a complex correlation between psychopathology and functioning such that the most severely impacted symptom domains are not necessarily those most predictive of adaptive functioning or caregiver strain. Finally, network modelling suggests 8 main axes of psychopathology in XYY syndrome, with core roles for overall symptom scores, inattention, and social difficulties.”
