By analyzing the effect of gene mutations on the structure and function of proteins with the database, to speculate the destructive mutants. It was found that individuals with the genotype of the five key SNP loci were more susceptible to tumors; these specific markers can be used as a molecular marker to determine the susceptibility of a tumor to the individual, and to diagnose the population with high risk of tumor; and rs201154887 can be used as a new disease molecular marker.展开更多
