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]

Submissions by phenotype

Immunodeficiency, common variable, 7 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingInvitaeAug 07, 2023For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 581865). This variant has not been reported in the literature in individuals affected with CR2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Gly262*) in the CR2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CR2 are known to be pathogenic (PMID: 26325596, 28499783). -
