Purpose:
To explore the association between MEG3 polymorphisms and the risk of prostate cancer in the Chinese Han population.
Materials And Methods:
Two MEG3 single-nucleotide polymorphisms (SNPs) (rs11627993 C >T rs7158663 A>G) were genotyped in a case-control study in which 165 prostate cancer patients and 200 healthy controls were recruited by a Real-Time Polymerase Chain Reaction (PCR) with the TaqMan assay. The odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the strength of association.
Results:
No statistically significant differences were found in the allele or genotype distributions of the MEG3 rs11627993 C >T and rs7158663 A > G polymorphisms among cases or healthy control subjects (rs11627993: CC vs CA: 95% CI = 0.54-1.95, ORs = 1.03; CC vs AA: 95% CI = 0.67-2.54, ORs = 1.30 ; CC/CA vs AA: 95% CI = 0.81-1.98, ORs = 1.26 , P = .29 ; C vs A: 95% CI = 0.85-1.57, ORs = 1.16, P = .35; rs7158663: AA vs AG: 95% CI = 0.76-5.08, ORs = 1.97, AA vs GG: 95% CI = 0.57-3.29, ORs = 1.37; AA/AG vs GG : 95% CI = 0.56-1.32, ORs = 0.86, P = .49; A vs G: 95% CI = 0.69-1.39, ORs = 0.98, P = .91) Further stratified analysis detected no significant association.
Conclusion:
The MEG3 polymorphisms (rs11627993 C>T and rs7158663 A>G) does not influence the susceptibility to prostate cancer.
