The common cause of several autosomal dominant diseases is an altered myosin heavy chain, which is an essential constituent of the cytoskeleton. Depending on the type of mutation different pathological findings might be present. Nephropathy, resembling Alport syndrome, deafness, and haematological findings, such as leukocyte inclusions and thrombocytopenia with giant platelets, might be present.
