Fc-Gamma Receptor 3B Copy Number Variation Is Not a Risk Factor for Behçet’s Disease

Table 2

Distribution of FCGR3B copy number (CN) variants in Behçet’s (BD, 𝑁=187) patients and controls (𝑁=178). When compared to 2 CN, there was no evidence that <2 CN or >2 CN genotypes were different in frequency between BD patients and controls (𝑃=0.16,0.50, resp.).

FCGR3B CN	BD	Controls
1	15 (8.0%)	22 (12.4%)
2	161 (86.1%)	143 (80.3%)
3	10 (5.3%)	12 (6.7%)
4	1 (0.5%)	1 (0.6%)
Total	187	178
