The p.V487M variant (also known as c.1459G>A), located in coding exon 5 of the RBM20 gene, results from a G to A substitution at nucleotide position 1459. The valine at codon 487 is replaced by methionine, an amino acid with highly similar properties. This variant has been detected in a pediatric dilated cardiomyopathy case; however details were limited (Pugh TJ et al. Genet Med, 2014 Aug;16:601-8). This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
