Xyy redirects here. For the CIE XyY colour model, see XyY. XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births.or the CIE XyY colour model, see XyY.

Klinefelter syndrome or Klinefelter's syndrome (KS) (/ËklaÉªnfÉltÉr/) also known as 47,XXY or XXY, is the set of symptoms that result from two or more X chromosome in males.The primary feature is sterility.Often symptoms may be subtle and many people do not realize they are affected.he underlying mechanisms involves at least one extra X chromosome in addition to a Y chromosome such that there is a total of 47 or more chromosomes rather than usual 46. KS is diagnosed by the genetic test known as a karyotype. While there is no cure a number of treatments may help.
