Genes affected

CR2 (HGNC:2336): (complement C3d receptor 2) This gene encodes a membrane protein, which functions as a receptor for Epstein-Barr virus (EBV) binding on B and T lymphocytes. Genetic variations in this gene are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 464 of the CR2 protein (p.Pro464Ser). This variant is present in population databases (rs41313740, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 473093). 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: "Probably 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. -
