Genetic errors linked to more ALS cases than scientists had thought

Genetic mutations may cause more cases of amyotrophic lateral sclerosis (ALS) than scientists previously had realized, according to researchers at Washington University School of Medicine in St. Louis and Cedars-Sinai Medical Center in Los Angeles. The scientists also showed that the number of mutated genes influences the age when the fatal paralyzing disorder first appears. ALS, also known as Lou Gehrig's disease, destroys the nerve cells that control muscles, leading to loss of mobility, difficulty breathing and swallowing, and eventually paralysis and death. Understanding the many ways genes contribute to ALS helps scientists seek new treatments.
