hereditary inclusion body myopathy

Hereditary inclusion body myopathies (HIBM) are a heterogeneous group of genetic disorders which have different symptoms. Generally, they are neuromuscular disorders characterized by muscle weakness developing in young adults. Hereditary inclusion body myopathies comprise both autosomal recessive and autosomal dominant muscle disorders that have a variable expression (phenotype) in individual patients, but all share similar structural features in the muscles.
