Colorectal cancer (CRC) is categorized by alteration of vital pathways such as β-catenin (CTNNB1) mutations, WNT signaling activation, tumor protein 53 (TP53) inactivation, BRAF, Adenomatous polyposis coli (APC) inactivation, KRAS, dysregulation of epithelial to mesenchymal transition (EMT) genes, MYC amplification, etc. In the present study an attempt was made to screen CTNNB1 gene in colorectal cancer samples from Pakistani population and investigated the association of CTNNB1 gene mutations in the development of colorectal cancer. This evidence concerns the gene CTNNB1 and colorectal carcinoma.
