It is known that FcγRs mediate multiple immunological functions, which influence both innate and adaptive responses.46 Besides, FcγRs‐mediated antibody effector functions are compromised or suppressed during persistent viral infection.47, 48 FcγRs are classified into CD64 (FcγR I), CD32 (FcγR II) and CD16 (FcyR III) depending on their affinity and structure. Here, FCGR1A is linked to viral infectious disease.
