A very recent study involving over 120 centers globally studied 2180 cases of IPF using whole-genome sequencing to investigate the role of rare variants on IPF risk found that rare variants within the telomerase reverse transcriptase (TERT) and regulator of telomere length 1 (RTEL1) genes were significantly associated with IPF [18]. The gene discussed is TERT; the disease is idiopathic pulmonary fibrosis.
