UBQLN2 in familial amyotrophic lateral sclerosis in the Netherlands

Recently it was discovered that mutations in the UBQLN2 gene were a cause of an X-linked dominant type of familial amyotrophic lateral sclerosis (ALS). We investigated the frequency of mutations in this gene in a cohort of 92 families with ALS in the Netherlands. Eight families were excluded because of male-to-male transmission. In the remaining 84 familial ALS cases no mutations were discovered in UBQLN2. Hence, UBQLN2 was not found to be a cause of familial ALS in the Netherlands. (C) 2012 Elsevier Inc. All rights reserved
