Mutation responsible for cystic fibrosis also involved in muscle atrophy

Patients with cystic fibrosis (CF) usually experience significant muscle loss, a symptom traditionally considered to be a secondary complication of the devastating genetic disease. However, a recent study by Dr. Basil Petrof reverses the equation: his results show that muscle atrophy and weakness may be a primary symptom caused by the effects of CFTR gene mutations on the muscle itself. Dr. Petrof's findings will be published on July 31 in Public Library of Science -- Genetics.
