摘要:: The common G to A single nucleotide polymorphism (G870A) in the splice donor region of exon 4 enhances alternate splicing, and produces a longer half-life cyclin D1 (CCND1). This study was aimed at investigating the possible association between the G870A polymorphism in CCND1 and the risk of endometrial cancer.,We assessed the association between the CCND1 G870A polymorphism and the risk of endometrial cancer in a hospital-based case-control study among 231 Korean women (77 cases; 154 matched controls). Controls were matched to cases with respect to age, menopausal status, and hormone therapy status.,The allele frequencies of the case subjects (A, 0.45; G, 0.55) were significantly different from those of control subjects (A, 0.58; G, 0.42) (P = 0.008). All case and control subjects were in Hardy-Weinberg equilibrium. The AA genotype was associated with a significantly elevated odds ratio (OR) of 3.18 [95% confidence interval (CI) 1.38-7.37, P = 0.007], and the AG genotype was associated with an OR of 1.38 (95% CI 0.65-2.89). When we combined the GG and AG genotypes as a reference genotype, we found that the OR for the AA genotype was 2.53 (95% CI 1.34-4.80, P = 0.004), supporting a recessive model for the A allele. Conditional logistic regression adjusted for various risk factors of endometrial cancer revealed positive associations between the AA genotype and an increased risk of endometrial cancer (OR 3.16, 95% CI 1.18-8.43, P = 0.022). However, no significant difference in endometrial cancer stage or grade was observed between the CCND1 genotypes.,Our data suggest that the CCND1 polymorphism is associated with an increased risk of endometrial cancer. To validate this association, a large-scale population-based study is needed.
