Desmopathy is a rare hereditary disease associated with a mutation in the DES gene, which is a kind of myofibrillar myopathy. With this disease, it is possible to damage skeletal, cardiac, smooth muscles, as well as diaphragm. In clinical practice, desminopathy is a difficult diagnostic task. In this article, the clinical case of the family form of myofibrillar myopathy with the established mutation c.1021A> C (Thr341Pro) in the DES gene in the heterozygous state is considered. We present a family study in a cumulative calculus of over 100 years describing the dynamics of clinical manifestations, morphological, cardiological and electromyographic parameters.
