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] CIViC Summary for FCGR2A Gene
A study in humans identified the FCGR2A as a core hub gene within a seven-gene blood molecular signature for differentiating sepsis-induced acute lung injury from sepsis, where its expression was significantly correlated with ALI score and it was highly expressed in monocytes, HSC_-G-CSF, and platelets based on single-cell RNA sequencing analysis [Sun et al. DOI:10.1016/j.ijbiomac.2024.136961]. In a separate assessment of natural gene expression variation in human blood leukocytes, the FCGR2A was classified as a housekeeping gene in the immune function class and was found to be differentially expressed between monozygotic twins, belonging to the least variable category of expression [Sharma et al. DOI:10.1152/physiolgenomics.00228.2003]. In rats, a binge methamphetamine regimen significantly upregulated the FCGR2A in striatal and prefrontal cortex microglia/macrophages at 2 hours post-treatment, identifying it as an M1 polarization marker associated with the induced inflammatory state [Kays and Yamamoto DOI:10.3390/brainsci9120340].
