Description

The p.E921A variant (also known as c.2762A>C), located in coding exon 21 of the MYH7 gene, results from an A to C substitution at nucleotide position 2762. The glutamic acid at codon 921 is replaced by alanine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
