Klinefelter Syndrome Klinefelter syndrome is a genetic condition that occurs in males when they have an extra X chromosome. Most people have 46 chromosomes. Chromosomes contain all of your genes and DNA, the building blocks of the body. The 2 sex chromosomes (X and Y) determine if you become a boy or a girl. Girls normally have 2 X chromosomes. Boys normally have 1 X and 1 Y chromosome. Klinefelter syndrome results when a boy is born with at least 1 extra X chromosome. Usually, this occurs due to 1 extra X. This is written as XXY. Klinefelter syndrome occurs in about 1 out of 500 to 1,000 baby boys. Women who get pregnant after age 35 are slightly more likely to have a boy with this syndrome than younger women. Symptoms may include any of the following: Abnormal body proportions (long legs, short trunk, shoulder equal to hip size)

Klinefelter syndrome What is Klinefelter Syndrome? Klinefelter Syndrome is a chromosome abnormality that affects only boys/men. People with Klinefelter are born with at least one extra X chromosome. The male with Klinefelter will be born with 47 chromosomes in each cell, rather than the normal number of 46. Klinefelter Syndrome is also called 47, XXY syndrome. Some Klinefelter patients have 48, 49, or 50 chromosomes.

Klinefelter syndrome People with Klinefelter syndrome usually have two X chromosomes and one Y chromosome (47, XXY). Some people with Klinefelter syndrome have the extra X chromosome in only some of their cells; these people are said to have mosaic Klinefelter syndrome. It is estimated that about half of the time, the cell division error occurs during development of the sperm, while the remainder are due to errors in egg development.

Genetic Diseases Genetic Changes. Klinefelter syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People typically have two sex chromosomes in each cell: females have two X chromosomes (46,XX), and males have one X and one Y chromosome (46,XY).

Urology Conditions A baby with two X chromosomes (XX) is female. A baby with one X chromosome and one Y chromosome (XY) is male. Most males with Klinefelter syndrome, also called XXY males, have two X chromosomes instead of one. The extra X usually occurs in all body cells.

- Klinefelter syndrome is caused by an additional X chromosome in males (47,XXY). Clinical findings are nonspecific during childhood; thus, the diagnosis commonly is made during adolescence or adulthood in males who have small testes with hypergonadotropic hypogonadism and gynecomastia.

- 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 symptoms had an extra sex chromosome, XXY instead of the usual male arrangement of XY. Although, XXY is common, the syndrome itself is uncommon. Many men live out their lives without ever even suspecting that they have an additional chromosome.

- Klinefelter syndrome, also known as the XXY condition, is a term used to describe males who have an extra X chromosome in most of their cells. Instead of having the usual XY chromosome pattern that most males have, these men have an XXY pattern. Klinefelter syndrome is named after Dr. Henry Klinefelter, who first described a group of symptoms found in some men with the extra X chromosome.

- What Are the Signs & Symptoms of Klinefelter Syndrome? Not all boys with Klinefelter syndrome will have noticeable symptoms. Other boys can have symptoms that are physically apparent or problems with speech, learning, and development. Babies with Klinefelter syndrome typically have weak muscles, reduced strength, and quiet personalities.

What are common symptoms of Klinefelter syndrome (KS)? Symptoms of Poly-X KS. Males with poly-X Klinefelter syndrome have more than one extra X chromosome, so their symptoms might be more pronounced than in males with KS. In childhood, they may also have seizures, crossed eyes, constipation, and recurrent ear infections. Poly-KS males might also show slight differences in other physical features.

Waardenburg Syndrome Symptoms and Types Waardenburg syndrome type 2 is defined as having all the features of type 1 except dystopia canthorum. 77% of individuals with type 2 have hearing loss. Waardenburg syndrome type 3, or Klein-Waardenburg syndrome, is similar to type 1 but includes muscle contractures. Waardenburg syndrome type 4, or Waardenburg-Shah syndrome, is also similar to type 1 but includes Hirschsprung's disease (a gastrointestinal malformation).
