For the β-catenin gene, no statistical differences of expression levels were seen between the cancer and normal tissue in all the CHIT1 gene mutant and wild type groups (Figure 5 and Figure 6B); the expression level of C-myc in all the CHIT1 gene mutant and wild type groups had statistical differences between the cancer and normal tissues (Figure 5 and Figure 6C). Here, CHIT1 is linked to cancer.
