A rare case of isolated IBM — HNRNPA2B1associated myopathy with inclusion bodies

Abstract

Hereditary inclusion body myopathy (IBM) is a variant of multisystem proteinopathy. It is a generalized progressive disease with autosomal recessive or autosomal dominant inheritance, characterized by the development of a degenerative process in muscle fi bers due to the accumulation of rimmed vacuoles and nuclear intermediate fi laments. This article presents a clinical observation of a rare variant of IBM — HNRNPA2B1-associated myopathy with a phenotypically diverse picture in representatives of one family from diff erent generations.
