Table 2.

FcγRIIIb allotype gene frequency

Population Gene frequency

NA1 NA2
Total 0.36 0.64
Control 0.39 0.61
RA 0.34 0.66

The Hardy–Weinburg formula was used to determine Fcγ receptor (FcγR)IIIb NA1 NA2 allotype gene frequency. There was no difference in distribution between RA and control populations (p > 0.05).
