Association of EZH2 Genotypes With Oral Cancer Risk.

ABSTRACT:

Background/aim

The over-expression of enhancer of zeste homolog 2 (EZH2) protein is found in oral cancer tissues. However, the genetic role of the enhancer of EZH2 in the etiology of oral cancer is unknown. The aim of this study was to evaluate the association of EZH2 genotypes with oral cancer risk among Taiwanese.

Materials and methods

Three polymorphic variants of EZH2, rs887569 (C to T), rs41277434 (A to C), and rs3757441 (T to C), were analyzed regarding their association with oral cancer risk among 958 oral cancer patients and the same number of healthy controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). In addition, the interaction of EZH2 rs887569, rs41277434, and rs3757441 genotypes with personal behaviors such as smoking, alcohol drinking, and betel quid chewing were also examined.

Results

The EZH2 genotypes rs887569, rs41277434, and rs3757441, were not significantly associated with oral cancer risk (p for trend=0.1735, 0.5658, and 0.4606, respectively). The analysis of allelic frequency distribution also supported the findings that the variant alleles at EZH2 rs887569, rs41277434, and rs3757441 may not serve as determinants of oral cancer risk (all p>0.05). There was no interaction between EZH2 rs887569, rs41277434, or rs3757441 genotypes with personal smoking, alcohol drinking or betel quid chewing behaviors.

Conclusion

EZH2 genotypes cannot predict oral cancer risk in Taiwan.
