RCV000182817 | SCV000235203 | uncertain significance | not provided | 2017-05-16 | criteria provided, single submitter | clinical testing | A variant of uncertain significance has been identified in the RYR2 gene. The V4125F variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The V4125F variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. In silico analysis predicts this variant is probably damaging to the protein structure/function. The V4125F variant is located in one of the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variants occur (Medeiros-Domingo et al., 2009). However, this substitution occurs at a position where amino acids with similar properties to valine are tolerated across species. |
