Description

The p.A391G variant (also known as c.1172C>G), located in coding exon 14 of the RYR2 gene, results from a C to G substitution at nucleotide position 1172. The alanine at codon 391 is replaced by glycine, an amino acid with similar properties. This alteration has been reported in a whole exome sequencing cohort (Landstrom AP et al. Circ Arrhythm Electrophysiol, 2017 Apr;10:). 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.
