Triple X syndrome, also known by alternative names such as Trisomy X or Triplo X, is a disorder within chromosomes. Our bodies are composed of millions of cells and each cell contains 46 chromosomes inside of its nuclei, which acts as the "brain" for the individual cell. Of these chromosomes there are typically 2 sex chromosomes, if you are female you will have two X chromosomes, and if you are male you will have one X chromosome and one Y chromosome. When someone is diagnosed as having Triple X syndrome they have three X chromosomes, thus making it a disorder which effects females only.

It is a disorder that is inherited from generation to generation, thus those diagnosed with Triple X will not necessarily have children with the same disorder.

If a pregnant woman is concerned that her child may suffer from this disorder it can be diagnosed during pregnancy with amniocentesis and CVS which allows for genetic testing...
