The rs2275913 and rs8193036, two selected interleukin 17A (IL-17A) SNPs, were associated with an increased risk of CS-COPD (p < 0.01; OR = 2.91) and BS-COPD (p = 4.52 × 10−17, OR = 1.11; p = 3.15 × 10−17, OR = 1.11) [180]. The gene discussed is IL17A; the disease is chronic obstructive pulmonary disease.
