The Association of MYNN and TERC Gene Polymorphisms and Bladder Cancer in a Turkish Population

Researchers reported that, MYNN rs10936599 polymorphism is in strong or moderate linkage disequilibrium with SNPs within the 3q26.2 chromosomal regions that also include the TERC gene. In addition, it has been reported that MYNN rs10936599 had a strong cumulative association with bladder cancer risk, and TERC gene suppresses cell growth in bladder cancer cell lines. Therefore, we aimed to determine whether polymorphisms of MYNN rs10936599 and TERC rs2293607 play any roles for bladder cancer in the Turkish population in this study.

In this case-control study, 70 patients and 150 controls were investigated. Genotyping analysis was performed by polymerase chain reaction, restriction fragment length polymorphism and DNA sequencing techniques.

Genotype distribution between study groups for MYNN rs10936599 SNP was significantly different (P = .001); although there was no difference in genotype distribution for TERC rs2293607 SNP. In addition, patients with CT genotype and CT+TT genotype combination of MYNN SNP have a decreased risk for bladder cancer. Two times increased risk ratio on development of bladder cancer was obtained for CC genotype of the SNP (P = .001). Besides, it was found that genotype combination of GG+AG/CC versus AA/CC genotypes (TERC/MYNN)showed stronger correlation. We observed that statistically significant relationship between the C-G haplotypes of two polymorphisms and bladder cancer risk (P = .0001).

At the end of the study, we suggested that there may exist an association between a combination of MYNN rs10936599 and TERC rs2293607 polymorphisms and development of bladder cancer in Turkish population.
