Collection Method:clinical testing

The p.E687G variant (also known as c.2060A>G), located in coding exon 9 of the RBM20 gene, results from an A to G substitution at nucleotide position 2060. The glutamic acid at codon 687 is replaced by glycine, an amino acid with similar properties. This amino acid position is conserved. 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. -
