The M1975V variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The M1975V variant was not observed in approximately 6000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This substitution occurs at a position that is conserved across species. However, the M1975V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In silico analysis predicts this variant likely does not alter the protein structure/function. Missense mutations in nearby residues have not been reported, indicating this region of the protein may tolerate change. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant.The variant is found in ARRHYTHMIA panel(s).
Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000212981 SCV000272395 uncertain significance not specified 2016-02-10 criteria provided, single submitter clinical testing The p.Met1975Val variant in RYR2 has not been previously reported in individuals with cardiomyopathy, but has been identified in 6/66168 European chromosomes by the Exome Aggregation Consortium (ExAC,; dbSNP r s200318013). Computational prediction tools and conservation analysis do not pro vide strong support for or against an impact to the protein. In summary, the cli nical significance of the p.Met1975Val variant is uncertain.

Color Health, Inc RCV001170254 SCV001355401 uncertain significance Cardiomyopathy 2020-09-17 criteria provided, single submitter clinical testing This missense variant replaces methionine with valine at codon 1975 of the RYR2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in one family affected with familial atrial fibrillation (PMID: 31539150). However, this variant did not segregate with the disease. This variant has been identified in 15/247224 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.
