Description

The p.G50R variant (also known as c.148G>A), located in coding exon 1 of the EPM2A gene, results from a G to A substitution at nucleotide position 148. The glycine at codon 50 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is not well 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 variant remains unclear.
