We selected two datasets, one from Vanderbilt University (GSE135893) [25], composed of 10 control and 12 IPF donors, and another from our group at the University of Colorado (GSE161685), composed of 2 control and 2 IPF donors, stratified further by genotype for the MUC5B rs35705950 (G; T) variant [26]. Here, MUC5B is linked to idiopathic pulmonary fibrosis.
