A patient with Klinefelter's syndrome and genotype 47 XXY was abused and ostracized by his family during childhood. Later, this pattern was repeated by a series of homosexual lovers. The separate and interactive effects between genetic and psychosocial risk factors may account for this patient's subsequent psychosexual and personality disorders and reminds scholars of psychopathology of the importance of early detection and intervention. This single case study is presented for heuristic value, illustrative purposes, and serves as a link between mental health clinicians and sexologists.

Objective: Systemic lupus erythematosus (SLE) and Sjögren disease (SjD) are autoimmune diseases with significant female predominance. The prevalence of SLE is increased in Klinefelter syndrome (KS) compared with the general male population. Our study investigates the dose effects of extra X chromosomes on the development of SLE and SjD in KS and triple X syndrome compared with the general population.

The clinically identifiable causes of infertility can be found in the male or female partner or in both. The molecular pathophysiology of infertility still remains unclear in many cases but is increasingly being revealed by genetic analyses.

Objective: To compare the prevalence of neurodevelopmental and mental health diagnoses in a national sample of youth with sex chromosome trisomies (SCTs) with matched controls.
Methods: Patients in PEDSnet and a diagnosis code mapping to 47,XXY/Klinefelter syndrome (n = 1171), 47,XYY/Double Y syndrome (n = 243), or 47,XXX/Trisomy X syndrome (n = 262) were matched with controls using propensity scores. Generalized estimating equations computed odds ratios (OR) with 95% confidence intervals (CI) for the prevalence of diagnoses within the neurodevelopmental and mental health composites, psychotropic medication prescriptions, and encounters with behavioral health and therapy providers.

Introduction: The (EMB) theory, a major causal hypothesis of autism (ASD: autism spectrum disorder), attributes excess androgens during early development as one of the causes. While studies have generally followed the EMB theory in females at birth, the co-occurrence of ASD in males at birth has been observed in conditions that are assumed to be associated with reduced androgen action during early development, including Klinefelter syndrome (KS) and sexual minorities. ASD is also associated with atypical sensory sensitivity, synesthesia, and savant syndrome.
