However, the association of genetic variants with other respiratory conditions may represent novel findings: the association of intronic variant rs61667602 in CRHR1 with reduced risk of post inflammatory pulmonary fibrosis (OR = 0.84 [0.80–0.89]; P = 2.26× 10−12), “alveolar and parietoalveolar pneumonopathy” (OR = 0.80 [0.72–0.88]; P = 1.58 × 10−08) and IPF (OR = 0.87 [0.82–0.92], P = 7.5 × 10−07). Here, CRHR1 is linked to idiopathic pulmonary fibrosis.
