Although the FCGR2B SNP (FcγRIIB-187Ile>Thr, rs1050501) is not associated with asthma, BHR, and atopy in FBAT analyses, conditional logistic regression analyses showed that FCGR2B SNP is significantly associated with atopy and that the FcγRIIB-187Thr (allele frequency = 0.088) is a risk allele for atopy (P = 0.003, OR 1.758, 95% CI: 1.209–2.556) (Table 2). This evidence concerns the gene FCGR2B and asthma.
