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...
The research, published June 9 in the journal Genetics in Medicine(opens in new tab), included data from more than 207,000 men who provided information to the U.K. Biobank, a repository of genetic and health data from half a million U.K.-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% had a known diagnosis, and just 0.7% of the XYY men had a diagnosis. (The potential symptoms of having an extra Y chromosome can be very subtle, which may somewhat explain the difference in diagnosis rates, according to the Genetic and Rare Diseases Information Center(opens in new tab).)...
Previous estimates suggested that roughly 100 to 200 men out of every 100,000 are XXY, according to the National Human Genome Research Institute(opens in new tab), and an estimated 18 to 100 out of every 100,000 were thought to be XYY, the authors noted in their report.
In all, about 0.17% of the study participants had an extra sex chromosome, or about one in 580. However, the rate observed in the study might be slightly lower than that among the general population, the study authors noted in their report. That’s because U.K. Biobank volunteers tend to be healthier than the general population and have a lower-than-average incidence of genetic conditions.

How could that person not have committed suicide? Has he? Must have. Seriously, who could live?
That show was so weird, during the college years the TV lounge would be full of us kids, watching it, and unable to remember if we were high or not. ;^)
I actually have XYY. I discovered it bc I participated in a test for genealogy of known Cohens. Both are the same and both my fathers.
They used to think XYY were prone to being criminals and thugs and less intelligent. Not true. I went to MIT and not exactly a lifetime criminal, unless you count speeding.
What is true is male secondary sex traits are slightly exaggerated. So I am a bit taller than I should be, am rather hirsute, have a pronounced chin, and always gained muscle very easily from exercise. Tend to smell rather, dank of I don’t shower a lot.
I am going to go ahead and go out on a limb and post without actually reading the article. (I know, who does that?)
Yes, I have to confess that I am one of the relatively few men that have the “Alpha Male” chromosome.
[snip] Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects. [/snip]

There you have it:
The ‘Cassanova Chromosome’.
I’m blessed. /s
“Most without knowing”
Damn, and I always check my chromosomes - how did that one escape me,
I carried it once, across the threshold but other than that, she’s kinda heavy.
The nature of the double helix can be discerned through how the single non-helix gets used...

How’d you come out vis a vis the Cohens study?
[singing] Blame it on the Cassanova...
I thought all babies were initially ‘female’ (X) and then the dumb ones (Y) develop a penis at about 60 days in utero? ;)

*RIMSHOT* :)
Can you cash it in for extra sex?
Explains why so many republican men in DC are such spineless wusses.
Whether XXY or XYY, the baby is born as a male, which means a good definition of a man is “has at least one Y chromosome”.
I don’t get it...
