Tuberous sclerosis

A genetic disorder characterized by seizures, skin differences, benign tumors (tubers) that harden as the patient gets older, and developmental delays. Many children with tuberous sclerosis have autistic-like symptoms. Diagnosis is by observation of symptoms, particularly seizures combined with white spots on the skin that are most easily seen under ultraviolet light. Two genes associated with tuberous sclerosis have been found, one on chromosome 9, and one on chromosome 16, but genetic testing is not yet available. No treatment specifically for tuberous sclerosis is available, but surgery and medication can minimize associated problems.
