Amyotrophic lateral sclerosis(ALS) is a progressive neurodegenerative disease. The majority of ALS cases are sporadic with only about 20% of familial forms. Even in families with genetic predisposition, there is significant phenotypic variability, suggesting that ALS onset may be triggered by a combination of genetic factors, environmental factors(e.g., military service,
