Klinefelter Syndrome is one of the most common Chromosome disorders affecting males. Humans have 46 chromosomes including two chromosomes which determine sex. Females have two X chromosomes while males generally have an X and a Y chromosome. However, males affected by Klinefelter syndrome have an extra X chromosome. Consequently, Klinefelter’s patients are often referred to as XXY males or 47 XXY males. The syndrome was named Klinefelter after Dr Henry Klinefelter who first documented symptoms of men with an extra X chromosome. Klinefelter syndrome affects around one in five hundred males born.
