A preliminary study: MUC5B promoter polymorphism and its association with IPF

Abstract

Abstract Background The (T) allele of MUC5B gene is strongly correlated with idiopathic pulmonary fibrosis (IPF) and interstitial lung diseases (ILD) related to autoimmune conditions in Caucasians, but no data is available regarding this polymorphism in the Egyptian patients. Results This study is an observational cross-sectional study; the percentage of the (T) allele of MUC5B gene promoter in normal Egyptian persons in this study was 20%. This polymorphism is strongly related with risk for development of UIP/IPF in Egyptian patients compared to the other 2 groups (P value < 0.001). The MUC5B polymorphism has no role for developing interstitial lung disease in autoimmune diseases. Conclusions This study showed the potential role of MUC5B promoter polymorphism in IPF patients. Further multicentric studies are essential to be conducted deploying larger cohorts and different ethnic populations for further evaluation of these polymorphisms correlation.
