Abstract

Creatine transporter deficiency is an X-linked disorder characterized by mental retardation and language delay. The authors report a patient affected by creatine transport deficiency caused by a novel mutation in the SLC6A8 gene. Impairment in social interaction represents a consistent clinical finding in the few cases described to date and may be a diagnostic clue for creatine transporter deficiency in males affected by mental retardation, seizures, and language impairment.
