Two samples failed genotyping of FCGR3A and 2 samples failed in genotyping of FCGR2B. Allele distributions of the tested FCGR genes in the control group were in Hardy-Weinberg equilibrium. The frequencies of FCGR2A, FCGR3A, FCGR3B and FCGR2B genotypes were shown in Table 2 . An association was found between FCGR2B 232I/T genotypes and cryptococcal meningitis based on dominant and over-dominant model. The FCGR2B 232I/I genotype was over-presented (OR = 1.652, 95% CI [1.02-2.67]; P = 0.039) and the FCGR2B 232I/T genotype was underpresented (OR = 0.542, 95% CI [0.33-0.90]; P = 0.016) in patients with cryptococcal meningitis in comparison with controls. No significant difference was found in the distribution of FCGR2A 131H/R, FCGR3A 158 F/V and FCGR3B NA1/NA2 genotypes.
