The genetic association of genetic polymorphisms in MUC5B-MUC2-TOLLIP as well as TERT and TERC loci with high risk for pulmonary fibrosis has been confirmed by recent results from GWAS comparing 4683 controls and 1616 cases of fibrotic idiopathic interstitial pneumonias (IIP) including 77% of IPF cases with independent replication cohort (Fingerlin et al., 2013). The gene discussed is MUC2; the disease is idiopathic pulmonary fibrosis.
