Amyotrophic lateral sclerosis type 3

Summary

Amyotrophic lateral sclerosis-3 (ALS3) is a neurodegenerative disorder characterized by the death of motor neurons in the cortex, brainstem, and spinal cord, resulting in progressive muscle weakness and atrophy and death from respiratory failure, usually within 3 to 5 years of symptom onset (Brown, 1995). For a phenotypic description and a discussion of genetic heterogeneity of amyotrophic lateral sclerosis, see ALS1 (105400). [from OMIM]
