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 ]]> First recurrent large genomic rearrangement in the BRCA1 gene found in Poland https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:21290 BRCA1 gene increases the risk of the person developing breast and/or ovarian cancer. The prevalence and spectrum of large genomic rearrangements (LGRs) varies considerably among different tested populations. In our previous study we described three LGRs in BRCA1 (exons 13-19, exon 17 and exon 22) in Polish families at high risk of breast and ovarian cancer. In this study we analyzed a group of 550 unselected women with ovarian cancer for the three previously identified LGRs. We used a rapid, single-step and closed-tube method: high-resolution melting analysis (HRMA). In this group of unrelated patients diagnosed with ovarian cancer we found three cases with the same deletions of exon 22. This is the first recurrent large deletion in BRCA1 found in Poland. We conclude that screening for the exon 22 deletion in BRCA1 should be included in the Polish BRCA1 genetic testing panel and possibly extended into other Slavic populations.]]> Sat 24 Mar 2018 07:54:36 AEDT ]]> Low prevalence of CDKN2A/ARF mutations among early-onset cancers of breast, pancreas and malignant melanoma in Poland https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5178 g), a novel intronic change IVS1+36 g>c and two common variants A148T and IVS3+29 c>g. The results of this study revealed a paucity of mutations in CDKN2A/ARF suggesting that in the Polish population this gene does not contribute significantly to early-onset breast cancer, pancreatic cancer and malignant melanoma.]]> Sat 24 Mar 2018 07:47:42 AEDT ]]> Germline mutations in the CHEK2 kinase gene are associated with an increased risk of bladder cancer https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5018 Sat 24 Mar 2018 07:44:12 AEDT ]]> The VEGF_936_C > T 3 ' UTR polymorphism reduces BRCA1-associated breast cancer risk in Polish women https://nova.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 ]]>
