The frequencies of the AA genotype and A allele of rs13210247/TRAF3IP2 were significantly lower in BD patients (pc = 1.61×10−7, OR = 0.391; pc = 2.07×−7, OR = 0.417 respectively) while the frequency of the AG genotype and G allele was higher compared with controls (pc = 7.05×10−8, OR = 2.626; pc = 2.07×10−7, OR = 2.396 respectively) (Table 1). Here, TRAF3IP2 is linked to Behcet disease.
