MACROD2 and colorectal carcinoma: We computationally analyzed the CNV data to select the crucial SNP sites showing the most relevance to the four Dukes stages of CRC (A, B, C, and D) and three different states of MACROD2 (heterozygous deletion, homozygous deletion, and normal state), suggesting that these CNVs may play functional roles in CRC tumorigenesis.
