FCGR1A encodes a protein that plays an important role in the immune response. This protein is a high-affinity Fc-gamma receptor. The gene is one of three related gene family members located on chromosome 1 FCGR1A (Fc Fragment Of IgG Receptor Ia) is a Protein Coding gene. Diseases associated with FCGR1A include Cervical Adenitis and Tetrasomy 21. Among its related pathways are Hematopoietic cell lineage and CDK-mediated phosphorylation and removal of Cdc6.
