XYY syndrome is a rare chromosomal birth defect that occurs when a male infant is born with an extra Y chromosome. Instead of having one X and one Y sex chromosome, those with XYY syndrome have one X and two Y chromosomes. Sex chromosome abnormalities like XYY syndrome are some of the most common chromosome abnormalities. XYY syndrome (also called Jacob's syndrome, XYY karyotype, or YY syndrome) affects only males. According to the National Institutes of Health (NIH), the condition occurs in about one in 1,000 live births, with five to 10 boys with XYY syndrome born daily in the United States.
