CD16A (FCGR3A) F158V Polymorphism Analysis
Also known as: Fc engineered monoclonal antibody, 158 F allele, V176F, Missense mutation, Phe158Val
Use
The CD16A (FCGR3A) gene encodes an Fc‑gamma receptor on human white blood cells, playing a critical role in antibody‑dependent cell‑mediated cytotoxicity (ADCC). In cancer patients, differential clinical responses to therapeutic monoclonal antibodies have been correlated with CD16A (FCGR3A) genotypes (V/V, F/V, or F/F) at SNP rs396991 (T>G, resulting in phenylalanine to valine at position 158) (PMID: 23286345; 30374078; 33480963).
