Klinefelter syndrome is a fairly common genetic condition found in males only. Many boys with Klinefelter syndrome — also known as XXY syndrome — have no signs or symptoms, and some don't even know they have it until later in life. The XXY condition that causes Klinefelter syndrome can't be changed, but medical treatment and working with therapists can help a boy's development and help lessen the condition's effects. Even without treatment, most boys with Klinefelter syndrome grow up to live productive, healthy lives. Boys who have Klinefelter syndrome are born with it. It's also called XXY because they have an extra X chromosome in most or all of their cells.
