We confirmed genome-wide significant associations with IPF susceptibility for 11 ofthe 17 previously reported signals (in or near TERC, TERT, DSP,7q22.1, MUC5B, ATP11A, IVD, AKAP13, KANSL1, FAM13A, andDPP9; Table E1 and Figure E4). The gene discussed is MUC5B; the disease is idiopathic pulmonary fibrosis.
