Klinefelter Syndrome is a chromosome abnormality that affects only boys/men. People with Klinefelter are born with at least one extra X chromosome. The male with Klinefelter will be born with 47 chromosomes in each cell, rather than the normal number of 46. Some Klinefelter patients have 48, 49, or 50 chromosomes.
What is the cause of the chromosome aberration in Klinefelter's syndrome? Certain chromosome aberrations appear more frequently in children of elderly mothers and, to a certain extent, also elderly fathers, but this is not the case of Klinefelter's syndrome, and today nothing definite is known about causes leading to an increase in the number of X-chromosomes as found in Klinefelter's syndrome.
