Illumina Clinical Services Laboratory,Illumina RCV000308159 SCV000356273 uncertain significance Arrhythmogenic right ventricular dysplasia, familial, 2 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Invitae RCV000362879 SCV000637560 likely benign Catecholaminergic polymorphic ventricular tachycardia 2019-12-31 criteria provided, single submitter clinical testing
GeneDx RCV000605932 SCV000729740 likely benign not specified 2017-11-01 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Integrated Genetics/Laboratory Corporation of America RCV000605932 SCV001362141 benign not specified 2019-04-16 criteria provided, single submitter clinical testing Variant summary: RYR2 c.4044G>A alters a conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00015 in 280186 control chromosomes, predominantly at a frequency of 0.0037 within the Ashkenazi Jewish subpopulation in the gnomAD database. The observed variant frequency within Ashkenazi Jewish control individuals in the gnomAD database is approximately 61 fold of the estimated maximal expected allele frequency for a pathogenic variant in RYR2 causing Arrhythmia phenotype (6e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Ashkenazi Jewish origin. To our knowledge, no occurrence of c.4044G>A in individuals affected with Arrhythmia and no experimental evidence demonstrating its impact on protein function have been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (1x VUS, 3x likely benign). Based on the evidence outlined above, the variant was classified as benign.
