Some individuals have been reported with KS who also have other chromosome abnormalities, such as Down syndrome. Nondisjunction occurs when homologous chromosomes, in this case the X and Y or two X sex chromosomes, fail to separate, producing a sperm with an X and a Y chromosome sindroome an egg with two X chromosomes.

Genetic testing karyotype [4]. The syndrome is also the main cause of male hypogonadism.

While no cure is known, a number of treatments may help. Advanced reproductive assistance is sometimes possible. Affected males are often infertileor may have reduced fertility. Considering the names of all three researchers, it is sometimes also called Klinefelter-Reifenstein-Albright syndrome. The last reports revealed distinct genetic mechanisms of the two conditions that reinforce the coincidental mlinefelter of 1 uniparental maternal heterodisomy of chromosome 15 and paternal X-Y chromosome non-disjunction 3 or 2 paternally inherited microdeletion of chromosome 15 and maternal X-X inherited meiosis 1 non-disjunction 4,5.
