- Klinefelter syndrome is a genetic disorder that affects males. Klinefelter syndrome occurs when a boy is born with one or more extra X chromosomes. Most males have one Y and one X chromosome. Having extra X chromosomes can cause a male to have some physical traits unusual for males. Many men with an extra X chromosome are not aware that they have it, and they lead normal lives. Klinefelter syndrome occurs in about 1 out of 1,000 males.

Klinefelter Syndrome Chromosomes contain all of your genes and DNA, the building blocks of the body. Two sex chromosomes determine if you become a boy or a girl. Girls normally have two XX chromosomes. Boys normally have an X and a Y chromosome. Klinefelter syndrome is when a boy is born with at least one extra X chromosome. Usually, this occurs due to one extra X. This would be written as XXY.

Everything You Should Know About Klinefelter Syndrome Klinefelter syndrome is one of the most common chromosome conditions in newborns. It affects between 1 in 500 and 1 in 1,000 newborn males. Variants of the disease with three, four, or more extra X chromosomes are less common. These variants affect 1 in 50,000 or fewer newborns. It’s possible that Klinefelter syndrome affects even more boys and men than statistics suggest. Sometimes symptoms are so mild that they go unnoticed.

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.

Learning About Klinefelter Syndrome Klinefelter syndrome is a condition that occurs in men as a result of an extra X chromosome. The most common symptom is infertility. Humans have 46 chromosomes, which contain all of a person's genes and DNA. Two of these chromosomes, the sex chromosomes, determine a person?s gender. Both of the sex chromosomes in females are called X chromosomes. (This is written as XX.) Males have an X and a Y chromosome (written as XY).

Marfan syndrome Estimates indicate about one in 3,000 to 5,000 individuals have Marfan syndrome. Each parent with the condition has a 50% risk of passing the genetic defect on to any child due to its autosomal dominant nature. Most individuals with Marfan syndrome have another affected family member.
