MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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. [provided by RefSeq, Jun 2010]
PHENOTYPE: Mutants show increased antibody response, passive cutaneous analphylaxis, autoantibodies and arthritis susceptibility. On C57BL/6, mice die by 9 months with anemia, proteinuria, glomerulonephritis, and inflammatory disease. A strain variant controls expression in germinal center B cells. [provided by MGI curators]
