Psychiatric Characteristics in a Self-Selected Sample of Boys With Klinefelter Syndrome

Abstract
BACKGROUND. Klinefelter syndrome is the most frequent chromosomal aneuploidy with a prevalence of 1 in 700. Klinefelter syndrome has been widely associated with cognitive impairment and language problems. No previous studies have systematically investigated the association of Klinefelter syndrome with psychiatric disorders in children and adolescents. To our knowledge, the only data available are from psychiatric inventories of adults with Klinefelter syndrome.
