Adult onset neurodegenerative disorder
Gene: ARSA
metachromatic leukodystrophies comprise several allelic disorders.In the late infantile form, onset is usually in the second year of life and death occurs before 5 years in most. Clinical features are motor symptoms, rigidity, mental deterioration, and sometimes convulsions. In the adult form of metachromatic leukodystrophy, initial symptoms, which begin after age 16, are usually psychiatric and may lead to a diagnosis of schizophrenia. Disorders of movement and posture appear late. Can be diagnosed biochemically - low ASA activity. Many cases.Created: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
