When cancer locations were analyzed separately different signals were detected (Table 2): 16 in right colon cancer (the most significant signal was located in the NTF3 gene), 7 in left colon cancer (the most significant signal was located in the ABCC12 gene), and 10 in rectal cancer (the most significant signal was located in BRD7 gene). This evidence concerns the gene ABCC12 and rectal cancer.
