Triple X Syndrome
Triple X Syndrome, also known as XXX Syndrome, is a genetic disorder affecting the sex chromosomes. Females generally posses two X chromosomes, one from each parents, but females affected by Triple X syndrome possess three X chromosomes. On average, Triple X Syndrome affects 1 in 1000 females. Triple X syndrome generally doesn’t occur due to inheritance, but is rather caused by an error in the formation of the gametes known as nondisjunction, resulting in the extra X chromosome. Another cause of Triple X Syndrome is an error in the development of the embryo.
Symptoms of Triple X syndrome vary from person to person. While some may show no visible signs or symptoms, others can be affected heavily. Typically, characteristics of Triple X syndrome fall into two main categories: physical and developmental. Females with Triple X Syndrome generally have taller statures as well as mild facial abnormalities such as skin folds covering the inner corners of the eyes, relatively smaller head size as well as weak muscle tone (hypotonia). Females with Triple X syndrome can also suffer from developmental issues, such as delayed motor, speech and language skills, as well as learning disabilities.
Triple X Syndrome is generally diagnosed prenatally through amniocentesis or chorionic villus sampling. If unusual symptoms are evident, blood tests which analyse the chromosomes can be used for diagnosis. However, since many people with Triple X Syndrome portray no symptoms, they can live their entire life without diagnosis.
Treatment for Triple X syndrome is based on symptoms. Some females who portray no symptoms can function normally without needing treatment. Females suffering from developmental disorders would require identical counseling and treatment to anyone else suffering from the same learning disability, such as therapists or different education. Female should also be periodically screened during childhood if early signs of Triple X Syndrome are present, in order to
