Description

The p.R1574Q variant (also known as c.4721G>A), located in coding exon 32 of the MYH7 gene, results from a G to A substitution at nucleotide position 4721. The arginine at codon 1574 is replaced by glutamine, an amino acid with highly similar properties. This variant has been detected in an individual from a hypertrophic cardiomyopathy cohort (Chida A et al. Heart Vessels, 2017 Jun;32:700-707). This amino acid position is highly 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.
