title: A protective role for common p21WAF1/Cip1 polymorphisms in human ovarian cancer.
abstract: The objective of this study was to compare the frequency of two common p21WAF1/Cip1 gene polymorphisms in ovarian cancer patients with that in age-matched controls, from a population originating from Eastern Scotland. Both polymorphisms were found significantly less frequently in both the constitutive and tumour tissue DNA of ovarian cancer patients (3/65; 4.6%), than in that from geographically and age-matched controls (25/186; 13.4%) (p=0.0495, chi2). Furthermore, we found no p21WAF1/Cip1 gene mutations in any of the tumours, reflected by a relatively low degree of loss of heterozygosity (LOH) at the chromosomal region where the gene maps, providing further evidence that the p21WAF1/Cip1 gene is not mutated in ovarian cancer. The data suggest however, that there may potentially be a protective function for the two p21WAF1/Cip1 gene polymorphisms in the population under study.
