Description

The p.E1152V variant (also known as c.3455A>T), located in coding exon 25 of the MYH7 gene, results from an A to T substitution at nucleotide position 3455. The glutamic acid at codon 1152 is replaced by valine, an amino acid with dissimilar properties. This alteration has been reported in a cardiomyopathy cohort and a genetic testing cohort; however, clinical details were limited (Homburger JR et al. Proc Natl Acad Sci U S A, 2016 06;113:6701-6; Walsh R et al. Genet Med, 2017 02;19:192-203). 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.
