ABCA12 and colorectal cancer: Upregulation of ABCA12, ABCA13, ABCB6, ABCC1, ABCC2 and ABCE1 genes was found by Hlavata et al. [14] in colorectal cancer samples when compared to normal tissues and Nymoen et al. [15] observed that ABCA13 mRNA overexpression was significantly related to shorter overall survival in metastatic ovarian serous carcinoma.
