amyotrophic lateral sclerosis type 4

ALS4 is a familial form of amyotrophic lateral sclerosis, a neurodegenerative disorder affecting upper and lower motor neurons and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of cases leading to familial forms. ALS4 is a childhood- or adolescent-onset form characterized by slow disease progression and the sparing of bulbar and respiratory muscles.
