| Invitae | RCV000646206 | SCV000767965 | uncertain significance | Brugada syndrome 4 | 2021-09-02 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine with proline at codon 529 of the CACNB2 protein (p.Ala529Pro). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and proline. This variant is present in population databases (rs373826838, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with CACNB2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. |
| Ambry Genetics | RCV002397259 | SCV002705659 | uncertain significance | Cardiovascular phenotype | 2022-02-14 | criteria provided, single submitter | clinical testing | The p.A529P variant (also known as c.1585G>C), located in coding exon 13 of the CACNB2 gene, results from a G to C substitution at nucleotide position 1585. The alanine at codon 529 is replaced by proline, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
