Klinefelter Syndrome News and Research

RSS
Klinefelter syndrome, also known as XXY syndrome, is a genetic disorder that involves an additional X sex chromosome in males. Physiologically, males inherit one X chromosome from their mothers and one Y chromosome from their fathers and thus possess XY. Males with Klinefelter syndrome have an additional X chromosome that is inherited from either the mother or the father and therefore have XXY.
