The Role of MDR1 (C3435T) Gene Polymorphism in Patients with Chronic Obstructive Pulmonary Disease Associated with Type 2 Diabetes Mellitus.

Chronic obstructive pulmonary disease is a multifactorial disease characterized by gene-gene interaction as well as environmental effects. The incidence of type 2 diabetes mellitus is proved to be higher in the presence of chronic obstructive pulmonary disease than in the case of its absence. We aimed to study the genotypes of MDR1 (C3435T) gene polymorphism and its relationship with clinical, instrumental, and laboratory parameters in chronic obstructive pulmonary disease associated with type 2 diabetes mellitus.
