Klinefelter’s Syndrome and Adults

Klinefelter’s Syndrome (KS) is  a common congenital condition (that means it is present at birth). It is found in around 1 in 600 live male births and is caused by the presence of one or more additional sex chromosomes. Chromosomes are genetic material. Males typically have one X and one Y chromosome (XY) and females have two X chromosomes (XX). People with KS have two X chromosomes and one Y chromosome (XXY). This is why the KSA refers to the condition as KS/XXY.

KS/XXY is diagnosed by a genetic blood test which identifies the karyotype i.e. the number, size and shape of the chromosomes.
