triple X syndrome

tri·ple X syn·drome

trisomy of the X chromosome; original observations (made in mental institutions) were seriously biased and the phenotypic changes spurious. Intelligence may be at the lower range of normal, stature is usually tall, there may be speech and behavioral problems. The outstanding feature of the syndrome is the occurrence of twin Barr bodies in a typical cell.
