Klinefelter’s Syndrome (KS)/XXY 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.
Although the condition is relatively common, its effects are not well understood.
