Invitae | RCV000646203 | SCV000767962 | uncertain significance | Brugada syndrome 4 | 2017-08-09 | 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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CACNB2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with cysteine at codon 488 of the CACNB2 protein (p.Arg488Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. |
