What is the life expectancy of a male 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.

What are signs of Klinefelter syndrome in children?

Signs and symptoms may include:

  • Taller than average stature.
  • Longer legs, shorter torso and broader hips compared with other boys.
  • Absent, delayed or incomplete puberty.
  • After puberty, less muscle and less facial and body hair compared with other teens.
  • Small, firm testicles.
  • Small penis.
  • Enlarged breast tissue (gynecomastia)

How would you test if a male has Klinefelter syndrome?

Blood or urine samples can reveal abnormal hormone levels that are a sign of 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.

What is the long term outlook for a child with Klinefelter syndrome?

Life expectancy is usually normal and many people with KS have normal life. There is a very small risk of developing breast cancer and other conditions such as a chronic inflammatory disease called systemic lupus erythematosus.

What is the survival rate of Klinefelter syndrome?

We found that Klinefelter syndrome was associated with a significant increase in mortality risk of 40% (hazard ratio, 1.40; 95% confidence interval, 1.13-1.74), corresponding to a significantly reduced median survival of 2.1 yr.

Is Klinefelter’s 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.

What is super male syndrome?

XYY syndrome is a rare chromosomal disorder that affects males. It is caused by the presence of an extra Y chromosome. Males normally have one X and one Y chromosome. However, individuals with this syndrome have one X and two Y chromosomes. Affected individuals are usually very tall.

What is male with Klinefelter syndrome?

Klinefelter syndrome is a genetic condition in which a boy is born with an extra X chromosome. Instead of the typical XY chromosomes in men, they have XXY, so this condition is sometimes called XXY syndrome. Men with Klinefelter usually don’t know they have it until they run into problems trying to have a child.

Can Klinefelter syndrome be passed onto offspring?

Causes of Klinefelter syndrome 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 classed as a disability?

Social Security Benefits 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 affect the brain?

Klinefelter syndrome (47, XXY) (KS) is a genetic syndrome characterized by the presence of an extra X chromosome and low level of testosterone, resulting in a number of neurocognitive abnormalities, yet little is known about brain function.

Does an extra Y chromosome make you a killer?

The court found that while an extra Y chromosome seems like a logical explanation for mutant-aggressive behaviour, there is not much evidence that links the X or Y chromosome to the deviant behaviour of serial killers. Gosavi Gajbe conducted a study looking at the role of chromosomes in criminality.

What is Jacobsen syndrome?

Jacobsen syndrome is a condition caused by a loss of genetic material from chromosome 11. Because this deletion occurs at the end (terminus) of the long (q) arm of chromosome 11, Jacobsen syndrome is also known as 11q terminal deletion disorder.

Is Klinefelter syndrome considered a disability?

Does Klinefelter syndrome affect intelligence?

While a small, but significant downward shift in mean overall IQ has been reported, the general cognitive abilities of patients with KS are not typically in the intellectual disability range. Most studies support that males with KS have an increased risk of language disorders and reading disabilities.

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.

What type of people get Klinefelter syndrome?

Klinefelter syndrome results when a boy is born with at least 1 extra X chromosome. 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.

Is Klinefelter syndrome a disability?

What does it mean when a male has an extra Y chromosome?

XYY syndrome is a genetic condition that occurs when a male has an extra copy of the Y chromosome in each of their cells (XYY). Sometimes, this mutation is only present in some cells. Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome.
