| Invitae | RCV001992794 | SCV002226827 | uncertain significance | Brugada syndrome 4 | 2021-01-13 | criteria provided, single submitter | clinical testing | 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: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with CACNB2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with valine at codon 433 of the CACNB2 protein (p.Leu433Val). The leucine residue is weakly conserved and there is a small physicochemical difference between leucine and valine. |
| Ambry Genetics | RCV002386795 | SCV002692891 | likely benign | Cardiovascular phenotype | 2019-05-14 | 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. |
