Triple+X+Syndrome

Triple X syndrome is a genetic disorder that exclusively affects females. Overall it is a very minor problem with effects ranging from little or no symptoms to various abnormalities. Triple X Syndrome is when a female has three X chromosomes in her cells instead of 2. Triple X syndrome is a relatively common cause of learning difficulties (language based disabilities such as dislexia especially). Females with Triple X syndrome have normal intelligence but their IQ's tend to be slightly lower than that of their brothers and sisters. Mental retardation is very rare. Infants and children with triple x syndrome sometimes have delayed acquisition of some motor skills and speech development. People with triple x syndrome are often tall, with possible delayed onset of puberty. Also, some have small heads and epicanthal folds (vertical skin folds over the corners of their eyes).
