Pathogenic mutations in MYH7 have been reported to cause a wide range of clinical expressions ranging from hereditary skeletal muscle diseases, including Laing distal myopathy [5] and myosin storage myopathy (MSM) with or without cardiac involvement, to isolated cardiomyopathies such as dilated cardiomyopathy [6], hypertrophic cardiomyopathy [7], and left ventricular non-compaction cardiomyopathy [8], depending on the residue of MYH7 that is affected [9]. The gene discussed is MYH7; the disease is dilated cardiomyopathy.
