Abstract
- Nonaka myopathy (NM) or distal myopathy with rimmed vacuoles (DMRV) is an autosomal recessively inherited neuromuscular disorder characterized by early adult-onset weakness of distal muscles, rimmed vacuoles in muscle biopsy, and mutations in the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene. The authors describe a patient with typical clinical features of NM confirmed by GNE mutation. Mutation analysis of the GNE gene revealed that the patient was a compound heterozygous for V572L and C13S mutations.
