Klinefelter syndrome is caused by an additional X chromosome. This chromosome carries extra copies of genes, which interfere with the development of the testicles and mean they produce less testosterone (male sex hormone) than usual.
Males have an X and a Y sex chromosome (XY). Klinefelter syndrome can be caused by: One extra copy of the X chromosome in each cell (XXY), the most common cause. An extra X chromosome in some of the cells (mosaic Klinefelter syndrome), with fewer symptoms.
Klinefelter syndrome is a genetic condition in which a boy is born with an extra X chromosome. Instead of the typical XY chromosomes in men, they have XXY, so this condition is sometimes called XXY syndrome.
Other intersex conditions, including the last four conditions listed above—complete androgen insensitivity, Klinefelter syndrome, Turner syndrome, and vaginal agenesis—usually do not result in ambigu- ous genitals and may not be recognized at birth.
Klinefelter syndrome or Klinefelter's syndrome (KS) (/ˈklaɪnfɛltər/) also known as 47,XXY or XXY, is the set of symptoms that result from two or more X chromosomes in males. The primary feature is sterility. Often symptoms may be subtle and many people do not realize they are affected.
