Controls were matched to cases by year of birth and BRCA1 mutation. Genotyping analysis was performed using PCR-based restriction fragment length polymorphism analysis. Odds ratios (OR) were calculated using conditional and penalized univariable and multivariable logistic regression. Results: A comparison of the genotype frequencies between cases and controls revealed no association of the PHB 3'UTR _CT+TT genotypes with ovarian cancer risk (ORadj 1.34; 95% CI, 0.59–3.11). Conclusion: Our data suggest that the PHB 3'UTR polymorphism does not modify ovarian cancer risk in women carrying one of the three Polish BRCA1 founder mutations.]]> Wed 11 Apr 2018 14:48:22 AEST ]]> Refined histopathological predictors of BRCA1 and BRCA2 mutation status: a large-scale analysis of breast cancer characteristics from the BCAC, CIMBA, and ENIGMA consortia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19379 Wed 11 Apr 2018 14:19:24 AEST ]]> The influence of the Cyclin D1 870 G>A polymorphism as an endometrial cancer risk factor https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4378 A, causes overexpression and supports uncontrollable cellular growth. This polymorphism has been associated with an increased risk of developing many cancers, including endometrial cancer. Methods: The 870 G>A polymorphisms (rs605965) in the cyclin D1 gene was genotyped in an Australian endometrial cancer case-control population including 191 cases and 291 controls using real-time PCR analysis. Genotype analysis was performed using chi-squared (χ²) statistics and odds ratios were calculated using unconditional logistic regression, adjusting for potential endometrial cancer risk factors. Results: Women homozygous for the variant cyclin D1 870 AA genotype showed a trend for an increased risk of developing endometrial cancer compared to those with the wild-type GG genotype, however this result was not statistically significant (OR 1.692 95% CI (0.939-3.049), p = 0.080). Moreover, the 870 G>A polymorphism was significantly associated with family history of colorectal cancer. Endometrial cancer patients with the homozygous variant AA genotype had a higher frequency of family members with colorectal cancer in comparison to endometrial cancer patients with the GG and combination of GG and GA genotypes (GG versus AA; OR 2.951, 95% CI (1.026-8.491), p = 0.045, and GG+GA versus AA; OR 2.265, 95% CI (1.048-4.894), p = 0.038, respectively). Conclusion: These results suggest that the cyclin D1 870 G>A polymorphism is possibly involved in the development of endometrial cancer. A more complex relationship was observed between this polymorphism and familial colorectal cancer.]]> Wed 11 Apr 2018 10:44:26 AEST ]]> Polymorphisms in a putative enhancer at the 10q21.2 breast cancer risk locus regulate NRBF2 expression https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28231 Wed 01 Aug 2018 14:52:20 AEST ]]> Polymorphisms in genes of the steroid hormone biosynthesis and metabolism pathways and endometrial cancer risk https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:9354 Sat 24 Mar 2018 08:36:33 AEDT ]]> BRCA1-associated breast and ovarian cancer risks in Poland: no association with commonly studied polymorphisms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:9541 Sat 24 Mar 2018 08:35:48 AEDT ]]> Genetic variation in mitotic regulatory pathway genes is associated with breast tumor grade https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20582 Sat 24 Mar 2018 07:55:36 AEDT ]]> Association of a common AKAP9 variant with breast cancer risk: a collaborative analysis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5128 T and N2792S, 8375A>G) to be associated with an allele dose–dependent increase in risk of familial breast cancer in a German population. We extended the analysis of AKAP9 M463I, which is in strong linkage disequilibrium with AKAP9 N2792S, to 9523 breast cancer patients and 13 770 healthy control subjects from seven independent European and Australian breast cancer studies. All statistical tests were two-sided. The collaborative analysis confirmed the association of M463I with increased breast cancer risk. Among all breast cancer patients, the combined adjusted odds ratio (OR) of breast cancer for individuals homozygous for the rare allele TT (frequency = 0.19) compared with GG homozygotes was 1.17 (95% confidence interval [CI] = 1.08 to 1.27, P = .0003), and the OR for TT homozygotes plus GT heterozygotes compared with GG homozygotes was 1.10 (95% CI = 1.04 to 1.17, P = .001). Among the combined subset of 2795 familial breast cancer patients, the respective ORs were 1.27 (95% CI = 1.12 to 1.45, P = .0003) and 1.16 (95% CI = 1.06 to 1.27, P = .001).]]> Sat 24 Mar 2018 07:48:55 AEDT ]]> The VEGF_936_C > T 3 ' UTR polymorphism reduces BRCA1-associated breast cancer risk in Polish women https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4736 T polymorphism in the VEGF gene and its association with sporadic breast cancer risk has been analyzed in various studies yielding conflicting results. To analyze the role of this polymorphism in modifying hereditary breast and ovarian cancer risks, we conducted a case-control study and genotyped 755 Polish BRCA1 carriers, including 319 breast cancer cases, 146 ovarian cancer cases, and 290 unaffected controls. The results revealed an association of the CT + TT genotypes with a reduced breast cancer risk (ORadj 0.63, 95% CI, 0.41-0.98; ORclustered 0.63, 95% CI, 0.48-0.83), and a potential effect on ovarian cancer risk (ORadj 0.62, 95% CI, 0.33-1.18; ORclustered 0.62, 95% CI, 0.47-0.83). Thus, the 936_C>T polymorphism appears to modify disease risks in BRCA1 carriers.]]> Sat 24 Mar 2018 07:21:09 AEDT ]]> Genes associated with histopathologic features of triple negative breast tumors predict molecular subtypes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24832 Sat 24 Mar 2018 07:15:11 AEDT ]]>
