MUC5B and interstitial lung disease: Furthermore, we investigated the association between MUC5B and DIILD and found that rs565375327 showed the lowest P value [screening cohort (26 patients); P = 3.58 × 10−3, EGFR-TKI-induced ILD subgroup (13 patients); P = 4.74 × 10−4] of the SNVs in MUC5B, suggesting that MUC5B may be a promising predictive marker for the risk of DIILD, particularly for EGFR-TKI-induced ILD as well as GALNT13.
