Klinefelter Syndrome Signs and Symptoms. Klinefelter syndrome affects around 1 in every 660 males. Symptoms of Klinefelter syndrome.

It is congenital, which means it is present from birth. Men with Klinefelter syndrome have an extra X chromosome. The normal male chromosome arrangement is 46XY, but for men with Klinefelter syndrome it is 47XXY. The term Klinefelter syndrome (KS) describes a group of chromosomal disorder in which there is at least one extra X chromosome to a normal male karyotype, 46,XY. XXY aneuploidy is the most common disorder of sex chromosomes in humans, with prevalence of one in 500 males. Other sex chromosomal aneuploidies have also been described, although they are much less frequent, with 48,XXYY and 48,XXXY Klinefelter Syndrome Carla Fedor, RN ----- Introduction . In 1942, Dr. Harry Klinefelter and his coworkers first described the combination of features that has come to be recognized as Klinefelter Syndrome. By the late 1950’s, researchers discovered that men with this group of

However, motile sperms in the ejaculate and even spontaneous pregnancies resulting from fathers with KS have been described, although such cases are rare. Klinefelter syndrome, 46/47, XXY or XXY syndrome is a disorder where the human males bear an extra X chromosome. In general females are characterized by the presence of two X chromosomes and males bear on X and one Y chromosome but in the individuals M.A. Ferguson-Smith, in Encyclopedia of Genetics, 2001. Klinefelter syndrome gets its name from a publication in 1942 by Klinefelter, Reifenstein, and Albright describing a series of patients with gynecomastia, small testes, aspermatogenesis, androgen deficiency, and increased levels of follicle stimulating hormone. Of particular interest at that time was the association of primary Klinefelter Syndrome‐XXY Definition Klinefelter syndrome is a chromosomal disorder that affects only males. People with this condition are born with at least one extra X chromosome. The syndrome was first identified and described in 1942 by Harry Fitch Klinefelter Jr., an American physician. Klinefelter syndrome (KS), also known as 47,XXY or XXY, is the set of symptoms that result from two or more X chromosomes in males. The primary features are infertility and small testicles. Often, symptoms may be subtle and many people do not realize they are affected. Sometimes, symptoms are more prominent and may include weaker muscles, greater height, poor coordination, less body hair
