The p.R567H variant (also known as c.1700G>A), located in coding exon 14 of the MYH7 gene, results from a G to A substitution at nucleotide position 1700. The arginine at codon 567 is replaced by histidine, an amino acid with highly similar properties. This variant has been detected in individuals with dilated cardiomyopathy (DCM) with and without features of noncompaction, some of whom had variants in other cardiomyopathy-related genes, and was reported to segregate with disease in a family with DCM (Pugh TJ et al. Genet Med, 2014 Aug;16:601-8; external communication). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
