Triple X syndrome, also called trisomy X or 47,XXX, is a genetic disorder that affects about 1 in 1,000 females. Females normally have two X chromosomes in all cells — one X chromosome from each parent. In triple X syndrome, a female has three X chromosomes.
Is Trisomy XA mutation?
Trisomy X is a genetic disorder, but it is not inherited. The presence of the extra X chromosome results from sporadic, random errors during the normal division of reproductive cells in one of the parents (nondisjunction during meiosis).
What research is being done on Triple X syndrome?
If triple X syndrome is suspected based on signs and symptoms, it can be confirmed by genetic testing — chromosome analysis using a blood sample. In addition to genetic testing, genetic counseling can help you gain comprehensive information about triple X syndrome.
Is Triple X syndrome a disability?
If physical or mental manifestations of Triple X Syndrome are keeping your child from functioning normally — or they are preventing you from performing full-time work — you may be eligible for Social Security disability benefits.
What is Edwards syndrome?

What is super male syndrome?
XYY syndrome is a rare chromosomal disorder that affects males. It is caused by the presence of an extra Y chromosome. Males normally have one X and one Y chromosome. However, individuals with this syndrome have one X and two Y chromosomes. Affected individuals are usually very tall.
