A comprehensive analysis of common genetic variation in MUC1, MUC5AC, MUC6 genes and risk of stomach cancer.

ABSTRACT:

Objective

MUC1, MUC5AC, and MUC6 are main constituents of the mucus barrier in the stomach, which protects the underlying epithelium from acid, proteases, mechanical trauma, and pathogenic microorganisms. Accumulating evidence implicates potential roles of MUC1, MUC5AC, and MUC6 genetic variation in the development of stomach cancer.

Methods

We evaluated the relationship between common genetic variations in these genes and stomach cancer risk, using an LD-based tagSNP approach in a population-based case-control study conducted in Warsaw, Poland, during 1994-1996. We genotyped 6, 8, and 14 tagSNPs in MUC1, MUC5AC, and MUC6 genes, respectively, among 273 cases newly diagnosed with stomach cancer and 377 controls.

Results

Each of the six tagSNPs tested across the MUC1 re
