XYY syndrome : ウィキペディア英語版 | XYY syndrome
XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births. Some medical geneticists question whether the term "syndrome" is appropriate for this condition because its clinical phenotype is normal〔 and the vast majority of XYY males do not know their karyotype.〔 Oxford Data Base — XYY total ascertainment: ~ 3% — 934 XYYs (801 XYYs + 133 XYY mosaics) in Britain (population 60 million)〕 ==Signs and symptoms==
