Pictures and Symptoms of Klinefelter's Syndrome - XXY or X-X-Y
Klinefelter's Syndrome is a genetic disorder that happens in 1 in every 500 to 1000 male births. Instead of the normal XY chromosomes, these individuals have and extra X chromosome making them XXY. The normal human genetic make up is 46XY. Males usually have one X and one Y chromosome, i.e. the chromosome constitution 46,XY. Males with Klinefelter's syndrome have two X chromosomes (47-XXY), in rare cases three (48-XXXY) or four (49-XXXXY) X-chromosomes. The X-chromosomes carry genes in terms of development of testicles, sex hormone production and physical sex development in general as well as to a certain extent also height growth. The extra chromosome(s) results in a series of issues:
