RCV000036663 | SCV000171431 | benign | not specified | 2014-03-13 | 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. |

RCV000381788 | SCV000356429 | benign | Catecholaminergic polymorphic ventricular tachycardia 1 | 2018-01-12 | 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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. |

RCV000036663 | SCV001519623 | benign | not specified | 2021-03-15 | criteria provided, single submitter | clinical testing | Variant summary: RYR2 c.11476+15C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/4 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 0.001 in 205266 control chromosomes, predominantly at a frequency of 0.011 within the African or African-American subpopulation in the gnomAD database, including 6 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 320 fold of the estimated maximal expected allele frequency for a pathogenic variant in RYR2 causing Catecholaminergic Polymorphic Ventricular Tachycardia phenotype (3.4e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.11476+15C>T in individuals affected with Catecholaminergic Polymorphic Ventricular Tachycardia and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. |
