The p.E1026K variant (also known as c.3076G>A), located in coding exon 11 of the RBM20 gene, results from a G to A substitution at nucleotide position 3076. The glutamic acid at codon 1026 is replaced by lysine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species, and lysine is the reference amino acid in other 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. -
