PRNCR1 and colorectal carcinoma: To test this hypothesis, we selected five tag SNPs in the lncRNA PRNCR1 in the “gene-desert” region of 8q24 (i.e., rs1016343, rs13252298, rs7007694, rs16901946, and rs1456315), and genotyped the SNPs in a case–control study of 313 cases with CRC and 595 ethnicity-matched controls in a Chinese population.
