The purpose of this study is to explore the relationship between MKK4 gene promoter polymorphism and the incidence of colorectal cancer.This study will collect blood samples from patients with colorectal cancer and normal controls, extract DNA, use PCR to amplify MKK4 gene promoter polymorphic loci, and perform genetic typing. Further analysis of the relationship between genotype and risk of colorectal cancer.Expected results: MKK4 gene promoter polymorphism is significantly correlated with the incidence of colorectal cancer, and its variation may affect the expression and function of MKK4 gene, thereby playing a role in the incidence of colorectal cancer.Keywords: MKK4 gene; promoter region; polymorphism; colorectal cancer.
