Triple X Syndrome (47,XXX) Triple X Syndrome is a genetic disorder that alters the sex chromosomes. The X chromosome, along with the Y chromosome, determine the sex of an individual. Most males have only one X chromosome and one Y chromosome, while most females have two X chromosomes.
Triple X is a rare condition as it only happens to 1 in every 1000 females. This happens in women because of the additional X chromosome in the pair of XX chromosomes. The chromosomal pair determines the sex of the fetus. For female it is the XX chromosomes and males have the XY pair.
