Idiopathic Pulmonary Fibrosis Is Associated with Common Genetic Variants and Limited Rare Variants

The study investigated the role of rare genetic variants in the development of idiopathic pulmonary fibrosis (IPF), a rare and progressive lung disease. Using whole-genome sequencing, the researchers identified rare variants in TERT and RTEL1 genes significantly associated with IPF. They also estimated that the SNP heritability of IPF was 32%. The findings suggest that efforts in risk profiling or therapy development for IPF should focus on TERT, RTEL1, common variants, and environmental risk factors.
