Factors associated with adaptation to Klinefelter syndrome: the experience of adolescents and adults

Klinefelter syndrome (XXY), or 47,XXY, is a common genetic condition caused by the presence of an extra X chromosome in males. It is estimated to occur in one in 650 males, though population-based studies in the UK and Denmark have suggested that 65-75% of individuals with XXY are undiagnosed [1,2]. While the physical and cognitive phenotype associated with XXY is highly variable, common features include tall stature, language-based learning disabilities, disorders of executive function, hypogonadism, gynecomastia, and fertility problems [3].
