FCGR2A - Fc gamma receptor IIa Gene

Also Known as CD32; FCG2; FcGR; CD32A; CDw32; FCGR2; IGFR2; FCGR2A1; FcgammaRIIa

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 2212

About FCGR2A

Cytogenetic location: 1q23.3 Genomic coordinates (GRCh38): 1:161,505,457-161,524,048 (from NCBI)

This gene has 17 transcripts (splice variants), 263 orthologues, 17 paralogues and is associated with 3 phenotypes. Broad expression in appendix (RPKM 39.7), placenta (RPKM 36.5) and 21 other tissues.

Summary

This gene encodes one member of a family of immunoglobulin Fc receptor genes found on the surface of many immune response cells. The protein encoded by this gene is a cell surface receptor found on phagocytic cells such as macrophages and neutrophils, and is involved in the process of phagocytosis and clearing of immune complexes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2008]
