Figure 1(d) displayed the site of CNV alterations of 27 CRGs on chromosomes. We also analyzed the expression levels of CRGs in CRC and normal tissues and discovered that most CRG expression levels were linked to CNV changes (Figure 1(e)), and CRGs with CNV gains, such as YEATS2 and AHR, were significantly elevated in CRC samples. Here, YEATS2 is linked to colorectal carcinoma.
