MUC2 and idiopathic pulmonary fibrosis: Another mutation in the same gene family (Figure S1 in Supplementary Material) identified MUC2 rs79834606 as significantly associated in IPF (p = 3.8 × 10−6) with MAF (A-allele) 0.54 in IPF cases and 0.41 in controls (9), which is in accordance to our present findings (IPF: 0.40–0.58 and controls: 0.32) (Table S2 in Supplementary Material).
