Description

The p.R1149P variant (also known as c.3446G>C), located in coding exon 25 of the MYH7 gene, results from a G to C substitution at nucleotide position 3446. The arginine at codon 1149 is replaced by proline, 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.
