Genetic analysis of CHCHD10 in French familial amyotrophic lateral sclerosis patients.

Mutations in CHCHD10 have been reported as the cause of a large panel of neurologic disorders. To confirm the contribution of this gene to amyotrophic lateral sclerosis (ALS) disease, we analyzed the 4 coding exons of CHCHD10 by Sanger sequencing in a cohort of 118 French familial ALS already excluded for all known ALS-related genes. We did not find any pathogenic mutation suggesting that CHCHD10 is not a major genetic cause of familial ALS, in France.
