Ambry Genetics RCV002401143 SCV002706863 uncertain significance Cardiovascular phenotype 2020-07-30 criteria provided, single submitter clinical testing The p.R542H variant (also known as c.1625G>A), located in coding exon 4 of the JPH2 gene, results from a G to A substitution at nucleotide position 1625. The arginine at codon 542 is replaced by histidine, an amino acid with highly similar properties. This variant was detected in one individual in a sudden unexplained death cohort; clinical details were limited (Sanchez O et al. PLoS ONE, 2016 Dec;11:e0167358). This amino acid position is not well conserved in available vertebrate species, and histidine 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.
