| Ambry Genetics | RCV000618390 | SCV000737650 | likely benign | Cardiovascular phenotype | 2022-01-07 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV001255539 | SCV001432002 | likely benign | not specified | 2020-08-17 | criteria provided, single submitter | clinical testing | Variant summary: CACNA1C c.6011G>T (p.Gly2004Val) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.7e-05 in 246344 control chromosomes, predominantly at a frequency of 0.00015 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 15 fold of the estimated maximal expected allele frequency for a pathogenic variant in CACNA1C causing Timothy Syndrome phenotype (1e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. To our knowledge, no occurrence of c.6011G>T in individuals affected with Timothy Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Three ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance (2x) and likely benign (1x). Based on the evidence outlined above, the variant was classified as likely benign. |
