Nonaka myopathy, also known as hereditary inclusion body myopathy (HIBM) is an adult onset slowly progressive myopathy secondary to mutations in the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene that encodes a bifunctional enzyme which catalyzes the rate-limiting step in sialic acid biosynthesis. The presence of scattered small angular and atrophic fibers.
