Triple X syndrome

A chromosomal abnormality characterized by the presence of an additional X chromosome in each of a female's cells. Affected individuals may be taller than average but they typically do not have any unusual physical features and most experience normal sexual development and are fertile. Triple X syndrome is associated with an increased risk of LEARNING DISORDERS and delayed development of speech and language skills. Delayed development of motor skills, HYPOTONIA, and behavioral and emotional disturbances may also occur. SEIZURES or kidney abnormalities occur in about 10 percent of cases.

Also Known As:

47,XXX syndrome; 47,Xxx; Super female; Triple-X chromosome syndrome; Triple-X female; Triplo X syndrome; Trisomy X; XXX syndrome
