A previous study informed that rs35705950 is within an enhancer region of MUC5B that was differentially methylated and bound by the transcription factor FOXA2.52 Subsequent colocalization analyses with eQTL and mQTL data from control and IPF lung tissue revealed that the T allele of rs35705950 was also associated with higher methylation within a repressor region of MUC5B and higher MUC5B expression.28 Similarly, we found that MUC5B was the only eGene for rs35705950 in the lung. Here, MUC5B is linked to idiopathic pulmonary fibrosis.
