The observation of 26 years old patient with desminopathy declared itself by hypertrophied cardiomyopathy with its transformation into restrictive phenotype is presented. The features of pathologic course at the patient were a dominance and diversity of cardiac manifestations. Endomyocardiac biopsy allowed suspecting the desminopathy confirmed by genetic analysis. Morphological features of desmin-related cardiomyopathy were irregular desmin conglomerates mainly located under sarcolemma and an indirect histological signs of idiopathic cardiomyopathy as well nuclear polymorphism, perinuclear "nimbus", chaotic located myofibrils.

Desmin is a type III intermediate filament protein specifically expressed in muscle cells, which is encoded by the gene. Defects in the desmin protein and cytoskeletal instability may interfere with cardiac muscle conduction signals, a fundamental mechanism for arrhythmias in patients with desmin-related myopathy. This current case report presents a female patient in her early 20s who presented with early-onset complete atrioventricular block and complete left bundle branch block over the previous decade.

Myofibrillar myopathy (MFM) is a group of hereditary myopathies that mainly involves striated muscles. This study aimed to use tandem mass tag (TMT)-based proteomics to investigate the underlying pathomechanisms of two of the most common MFM subtypes, desminopathy and titinopathy. Muscles from 7 patients with desminopathy, 5 with titinopathy and 5 control individuals were included.
