Clinically, birth and development in affected females is normal until the age of 6-25 months, when progressive loss of voluntary control of hand movements and communication skills, ataxia, stereotypic hand movements, seizures, autistic behavior, intermittent hyperventilation, and hyperammonemia appear.
