Among these, three SNPs were shared among different IPF populations: first, rs35705950*T within promoter region of Mucin5B (MUC5B) was highly significant among all the IPF populations – Czech [OR (95% CI); p: 3.77 (7.47–1.9); 1.62 × 10−4]; German [4.83 (9.79–2.39); 1.55 × 10−5]; Greek [5.46 (10.82–2.76); 1.13 × 10−6]; French [6.77 (12.65–3.62); 5.28 × 10−10]; and combined IPF cases [5.23 (8.94–3.06); 1.80 × 10−11] (Table 2). The gene discussed is MUC5B; the disease is idiopathic pulmonary fibrosis.
