| Invitae | RCV001325804 | SCV001516810 | uncertain significance | Brugada syndrome 4 | 2023-04-05 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 171 of the CACNB2 protein (p.Ile171Val). 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1025487). This variant has not been reported in the literature in individuals affected with CACNB2-related conditions. This variant is present in population databases (rs140542975, gnomAD 0.02%). |
| Ambry Genetics | RCV002350603 | SCV002646503 | likely benign | Cardiovascular phenotype | 2021-08-31 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, 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. |
