The Evaluation Of rs11776042 Polymorphism Effect On Colorectal Cancer Risk In The Iranian Population: A Case-Control Study

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.

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)

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.

No significant difference was found in genotype and allele frequencies between the cases and controls for rs11776042 polymorphism in piRNA 015551 in our population.
