The expression level of mature mir-149 was examined in 55 normal thyroid tissue samples; (3) RESULTS: The CC genotype of rs2292832 was significantly associated with an increased risk of PTC compared with TT homozygote (OR = 1.60, 95% CI: 1.72-2.20, p = 0.003) and TT/TC combined genotype (OR = 1.54, 95% CI: 1.14-2.09, p = 0.005).
