In addition, comparison of the genes with somatic mutations in the normal-CRC, normal-colorectal adenoma groups, the Chinese study, the TCGA data, and African American CRC patients demonstrated that SOX9 and TP53 genes were common genes in the TCGA and Thai normal-CRC data, whereas the CTNNB1 gene was a common gene in the Thai normal-colorectal adenoma and TCGA data. This evidence concerns the gene CTNNB1 and colorectal carcinoma.
