Description

This missense variant replaces arginine with cysteine at codon 272 of the RYR2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in a proband affected with hypoplastic left heart syndrome, as well as in another four family members including two with confirmed heart diseases and two with normal echocardiograms (PMID: 33325730). This variant has been identified in 1/249146 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
