概要
49,XXXXY syndrome is a rare sex chromosome aneuploidy syndrome characterized by mental retardation, severe speech impairment, craniofacial abnormalities, multiple skeletal defects, and genital abnormalities. We describe a 13-year-old boy with 49,XXXXY syndrome, language impairment, seizures, and left-hemisphere magnetic resonance imaging abnormalities and review the distinctive neurologic, cognitive, and behavioral phenotypes associated with this disorder. Finally, we discuss testosterone supplementation in the treatment of this syndrome.
