A novel heterozygous deletion-insertion mutation in the desmin gene causes complete atrioventricular block and mild myopathy

Defects in the desmin gene have been identified in patients with cardiac and skeletal myopathy characterized by sarcoplasmic accumulation of desmin-positive deposits and electron dense granulofilamentous aggregates. We describe a desminopathy family with unusual clinical features of complete atrioventricular block and mild myopathy. The atrioventricular block can be found in each of the affected members sparing of the detectable cardiac...
