RCV002512999 | SCV003439368 | uncertain significance | not provided | 2022-03-24 | 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. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (PMID: 8621452). Experimental studies have shown that this missense change affects C2 function (PMID: 8621452). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant is also known as c.1330G>A (Gly444Arg). This missense change has been observed in individual(s) with C2 deficiency (PMID: 1542325, 8621452). This variant is present in population databases (rs151340617, gnomAD 0.002%). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 464 of the C2 protein (p.Gly464Arg). |
