XYY Syndrome (Jacobs syndrome)

The XYY Syndrome (Jacobs syndrome) results from a genetic abnormality which occurs due to the presence of an extra copy of Y chromosome in the male child. 

The usual symptoms associated with XYY syndrome include language difficulties and lower intelligence quotient. Learning disabilities, attention deficit disorder, behavioral problems, and hyperactivity, are also common. The affected boys usually grow tall.

Earlier, criminal behavior and aggressiveness were considered to be typical of men with XYY syndrome, but such link has been found to be absent.
