Mutations in a number of telomere-related genes, including TINIF2, nuclear assembly factor 1 (NAF1), dyskerin pseudouridine synthase 1 (DKC1) and regulator of telomere elongation helicase 1 (RTEL1), have been identified and associated with IPF and other interstitial lung diseases (ILDs) [35]. The gene discussed is DKC1; the disease is idiopathic pulmonary fibrosis.
