Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000038201 SCV000061869 uncertain significance not specified 2018-04-10 criteria provided, single submitter clinical testing proposed classification - variant undergoing re-assessment, contact laboratory
Color Diagnostics, LLC DBA Color Health RCV001183725 SCV001349535 uncertain significance Cardiomyopathy 2023-02-02 criteria provided, single submitter clinical testing This missense variant replaces valine with leucine at codon 72 of the PKP2 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 an individual affected with dilated cardiomyopathy (PMID: 27532257). This variant has been identified in 1/177540 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.
Invitae RCV001326326 SCV001517352 uncertain significance Arrhythmogenic right ventricular dysplasia 9 2022-08-18 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 72 of the PKP2 protein (p.Val72Leu). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with dilated cardiomyopathy (PMID: 27532257). ClinVar contains an entry for this variant (Variation ID: 45061). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
