"As many as one in 500 men may carry an extra sex chromosome – either an X or a
Y – but very few of them likely know about it, a new study suggests.
The research, published June 9 in the journal
Genetics in Medicine, included
data from more than 207,000 men who provided information to the UK Biobank, a
repository of genetic and health data from half a million UK-based
participants.
Typically, males carry one X- and one Y-shaped sex chromosome in each of their
cells, but among the study participants, there were 213 men who carried an
extra X chromosome and 143 that had an extra Y.
Very few of these men either reported being diagnosed with a chromosomal
abnormality or had such an abnormality noted in their medical records: Of the
XXY men, only 23 percent had a known diagnosis, and just 0.7 percent of the XYY
men had a diagnosis."
