Background: Recently, it has been shown that, piRNAs as a new class of non-coding RNAs (ncRNAs), play crucial roles in germline development and carcinogenesis. Despite this, the study on the effects of piRNAs polymorphism (piR-SNP) on colorectal cancer (CRC) risk is scarce. We evaluate the impact of rs11776042 in piRNA 015551 on CRC initiation and development in the Iranian population. Matherials & METHODS: The association of novel polymorphisms rs11776042 in piRNA 015551 gene with CRC risk using a case-control study on the Iranian population was estimated. All subjects were evaluated by TETRA primer-Amplification refractory mutation system polymerase chain reaction (TP-ARMS- PCR assay) Results: The genotypes frequency was 27%, 68% and 0.05% for C/C, C/T and T/T in controls and 31%, 65% and 0.04% in CRC patients respectively. The frequency of the C allele was 63% in patients versus 61% in controls and, T allele frequency was 37% in patients versus 39% in controls. Conclusion: No significant difference was found in genotype and allele frequencies between the cases and controls for rs11776042 polymorphism in piRNA 015551 in our population.
