Well established gene-disease association.
Alpers syndrome is an autosomal recessive disorder characterized by a clinical triad of psychomotor retardation, intractable epilepsy, and liver failure in infants and young children. Pathologic findings include neuronal loss in the cerebral gray matter with reactive astrocytosis and liver cirrhosis. The disorder is progressive and often leads to death from hepatic failure or status epilepticus before age 3 years.
