The UDP‐ N ‐acetylglucosamine 2‐epimerase/ N ‐acetylmannosamine kinase ( GNE ) gene is the causative gene for autosomal‐recessive hereditary inclusion‐body myopathy (h‐IBM). Two sisters affected with autosomal‐recessive h‐IBM were shown to be compound heterozygous for two novel GNE mutations: a large deletion involving exons 1—9, and a R162C amino acid change in the epimerase domain. This is the first deletion event observed in a GNE allele and expands the molecular pathogenesis of autosomal‐recessive h‐IBM. Muscle Nerve 28: 113–117, 2003
