Can Klinefelter syndrome be cured?
Currently, there is no way to remove chromosomes from cells to “cure” the XXY condition. But many symptoms can be successfully treated, minimizing the impact the condition has on length and quality of life. Most adult XXY men have full independence and have friends, families, and normal social relationships.
What gender is Klinefelter?
Klinefelter syndrome (sometimes called Klinefelter’s, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body.
Is Klinefelter syndrome serious?
Klinefelter syndrome is not necessarily anything serious, but treatment can help reduce some of the symptoms if necessary. In many cases, it’s only detected if a man with the condition undergoes fertility tests.
Which parent causes Klinefelter syndrome?
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.
Can Klinefelter syndrome cause death?
Mortality from all causes The mortality among KS men was 40% higher than that among population controls (hazard ratio, 1.40; 95% CI, 1.13–1.74; P = 0.002). The median survival age among KS subjects was 71.4 yr compared with 73.5 yr in controls, a difference of 2.1 yr (95% CI, 0.3–3.9; Fig. 1).
Is Klinefelter’s a disability?
Most males with the 47,XXY karyotype have normal intelligence. Intellectual disability occurs in males with Klinefelter syndrome variants, who have a higher number of X chromosomes. About 70% of patients have minor developmental and learning disabilities.
What causes Klinefelter?
Klinefelter syndrome is caused by an additional X chromosome. This chromosome carries extra copies of genes, which interfere with the development of the testicles and mean they produce less testosterone (male sex hormone) than usual.
