About FCGR2B

Cytogenetic location: 1q23.3 Genomic coordinates (GRCh38): 1:161,647,243-161,678,654 (from NCBI)

This gene has 6 transcripts (splice variants), 264 orthologues, 17 paralogues and is associated with 55 phenotypes. Biased expression in placenta (RPKM 92.9), appendix (RPKM 9.6) and 6 other tissues.

Summary

The protein encoded by this gene is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The encoded protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene.
