p.Gln1794Glu (CAG>GAG): c.5380 C>G in exon 37 of the MYH7 gene (NM_000257.2). The Gln1794Glu variant in the MYH7 gene has not been reported previously as a disease-causing mutation or as a benign variant, to our knowledge. Gln1794Glu results in a semi-conservative amino acid substitution of a neutral, polar Glutamine residue with a negatively charged Glutamic acid residue at a position that is conserved across species throughout evolution. In silico analysis predicts Gln1794Glu is damaging to the structure/function of the protein, and mutations affecting nearby residues (Asp1792Gly, Glu1801Gly) have been reported in association with DCM, supporting the functional importance of this region of the protein. The NHLBI ESP Exome Variant Server reports Gln1794Glu was not observed in approximately 5,000 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. Therefore, Gln1794Glu is a strong candidate for a disease-causing mutation, however the possibility that it is a benign variant cannot be excluded. The variant is found in DCM panel(s).
