How common is Klinefelters?

Klinefelter syndrome affects about 1 in 650 newborn boys. It is among the most common sex chromosome disorders, which are conditions caused by changes in the number of sex chromosomes (the X chromosome and the Y chromosome).

Can females get Klinefelter’s syndrome?

Klinefelter syndrome affects males only; females cannot have it. Klinefelter syndrome results from a genetic abnormality in which males have an extra copy of the X chromosome. Instead of the usual XY chromosomes, males with Klinefelter syndrome have an XXY pattern.

Can females have Klinefelter Syndrome?

Does Klinefelter syndrome affect teeth?

The X chromosome has been linked to enamel thickness as well as the rate of dental development (2, 16, 32, 39, 44-46). Consequently, males affected by KS have larger teeth than males with a normal chromosomal complement (19, 32, 36, 44, 47-49).

How long can a person live with Klinefelter’s syndrome?

Prognosis for Klinefelter Syndrome In general, life expectancy is normal. Some research has found that life expectancy for men with the condition may be a year or two less than those without it because of other health problems linked to Klinefelter.

What are the chances of getting Klinefelter syndrome?

Klinefelter syndrome affects 1 in 500 to 1,000 males. Variants of this condition are much rarer, occurring in 1 in 50,000 or fewer male births.

What is the prognosis for Klinefelter syndrome?

However, the prognosis of Klinefelter syndrome is good, provided the patient has careful and consistent monitoring of his health, as well as early treatment of any problems that occur. Many men with Klinefelter syndrome lead full and active lives, and can expect a normal lifespan.

What identifies a person as having 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.

What are the side effects of Klinefelter syndrome?

Klinefelter syndrome may adversely affect testicular growth, resulting in smaller than normal testicles, which can lead to lower production of testosterone. The syndrome may also cause reduced muscle mass, reduced body and facial hair, and enlarged breast tissue. The effects of Klinefelter syndrome vary,…
