Can Klinefelter syndrome be inherited?
Can Klinefelter syndrome be inherited?
Klinefelter syndrome is not directly inherited – the additional X chromosome occurs as a result of either the mother’s egg or the father’s sperm having the extra X chromosome (an equal chance of this happening in either), so after conception the chromosome pattern is XXY rather than XY.
Is Klinefelter syndrome inherited from mother or father?
Risk factors Klinefelter syndrome stems from a random genetic event. The risk of Klinefelter syndrome isn’t increased by anything a parent does or doesn’t do. For older mothers, the risk is higher but only slightly.
Does Klinefelter syndrome run in families?
Klinefelter syndrome isn’t passed down through families like some genetic diseases. Instead, it happens randomly from an error in cell division when a parent’s reproductive cells are being formed. If one of these cells is part of a successful pregnancy, a baby boy will have the XXY condition.
What is the risk for inheritance of Klinefelter syndrome?
Klinefelter syndrome is not inherited; the addition of an extra X chromosome occurs during the formation of reproductive cells (eggs or sperm) in one of an affected person’s parents.
What is the life expectancy of someone with Klinefelter syndrome?
According to research, Klinefelter syndrome can shorten your life expectancy up to two years. However, you can still live a long, full life with this condition. The earlier you get treatment, the better your outlook will be.
Is Klinefelter syndrome considered a disability?
If you or your dependent(s) are diagnosed with Klinefelter Syndrome and experience any of these symptoms, you may be eligible for disability benefits from the U.S. Social Security Administration.
Does Klinefelter syndrome cause mental retardation?
Klinefelter syndrome (KS) has not typically been associated with mental retardation (MR), however, in recent years a growing body of evidence suggested that KS boys often experience language deficits and academic difficulties.
Can you fix Klinefelter syndrome?
Although there’s no way to repair the sex chromosome changes due to Klinefelter syndrome, treatments can help minimize its effects. The earlier a diagnosis is made and treatment is started, the greater the benefits.

What causes the Klinefelter disorder?
Klinefelter syndrome is caused by a random genetic error that occurs during the formation of the egg or sperm, or after conception. Most commonly, Klinefelter syndrome occurs due to a process referred to as nondisjunction in the egg or the sperm during meiosis.
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,…
How do you test for Klinefelter syndrome?
Chromosome analysis. Also called karyotype analysis, this test is used to confirm a diagnosis of Klinefelter syndrome. A blood sample is sent to the lab to check the shape and number of chromosomes. The diagnosis can be confirmed by checking a sample of blood for the presence of the extra X chromosome .
