Sex differences in psychiatric disorders: what we can learn from sex chromosome aneuploidies

Article Title: Sex differences in psychiatric disorders: what we can learn from sex chromosome aneuploidies

Authors: Green, Flash, and Reiss

Date of Publication: January 2019

“The study of individuals with sex chromosome aneuploidies provides a promising framework for studying sexual dimorphism in neurodevelopmental and psychiatric disorders. Here we will review and contrast four syndromes caused by variation in the number of sex chromosomes: Turner syndrome, Klinefelter syndrome, XYY syndrome, and XXX syndrome. Overall we describe an increased rate of attention deficit hyperactivity disorder and autism spectrum disorder, along with the increased rates of major depressive disorder and anxiety disorders in one or more of these conditions. In addition to contributing unique insights about sexual dimorphism in neuropsychiatric disorders, awareness of the increased risk of neurodevelopmental and psychiatric disorders in sex chromosome aneuploidies can inform appropriate management of these common genetic disorders.”

Changes in the cohort composition of TS, severe non-diagnosis of KS, 47,XXX and 47,XYY syndrome

Article Title: Changes in the cohort composition of Turner syndrome and severe non-diagnosis of Klinefelter, 47,XXX and 47,XYY syndrome: a nationwide cohort study

Authors: Claus H. Gravholt, MD, PhD et al

Date of Publication: January 14, 2019

“The prevalence of TS is higher than previously identified, and the karyotypic composition of the TS population is changing. Non-diagnosis is extensive among KS, Triple X and Double Y, whereas all TS seem to become diagnosed. The diagnostic activity has increased among TS with other karyotypes than 45,X as well as among KS and Double Y.”

Neurocognitive functioning and risk for psychopathology in sex chromosome trisomy

Article Title: A review of neurocognitive functioning and risk for psychopathology in sex chromosome trisomy (47,XXY, 47,XXX, 47,XYY)

Authors: Sophie van Rijn, PhD

Date of Publication: March 2019

This paper reviews studies that illustrate an increased risk for social, emotional and behavioral problems in individuals with 47,XXY47,XXX, or 47,XYY. The primary focus of research in this area has been on language and learning problems; more recent research suggests that impairments in executive functioning, social cognition and emotion regulation may also be key factors underlying the risk for behavioral problems and mental disorders. Directions for future research are provided.

Authors: S. van Rijn, L. Stockmann, G. van Buggenhout, C. van Ravenswaaij-Arts, and H. Swaab

Date of Publication: 2014

This 2014 paper by Dr. Sophie van Rijn is an excellent study on the Theory of Mind and “the reported social behavioral difficulties in individuals with an extra X chromosome include shyness, social withdrawal, social anxiety, social immaturity, difficulties in peer relationships, social impulsivity, communication difficulties, reduced social assertiveness and difficulties with ‘being sensitive and responsive to the feelings and rights of others.”

“Individuals with an extra X chromosome are at increased  risk for autism symptoms. This study is the first to assess theory of mind and facial affect labeling in children with an extra X chromosome.”
