Role of Deleterious Rare Alleles for Acute-Onset Diffuse Interstitial Lung Disease in Collagen Diseases.

Acute-onset diffuse interstitial lung disease (AoDILD) includes acute exacerbation of interstitial lung disease (ILD), drug-induced ILD, and Pneumocystis pneumonia in collagen diseases patients. As AoDILD causes a poor prognosis in collagen disease patients, the pathogenesis of AoDILD should be investigated. Exome sequencing studies revealed that rare variants were detected to be causative in some diseases. Recently reported upregulated genes in acute exacerbation of idiopathic pulmonary fibrosis could provide candidate genes for restricted exome analysis of AoDILD in collagen disease. Here, we investigated rare variants in the coding and boundary regions of these candidate genes in AoDILD.
