Only approximately 50% of all familial breast cancers can be explained by known genetic factors, including mutations in BRCA1 and BRCA2. One of the most extensively studied candidates for breast and/or ovarian cancer susceptibility is BARD1. Although it was suggested that large mutations may contribute substantially to the deleterious variants of BARD1, no(More)
Loss of heterozygosity atBRCA1/2 loci in breast and ovarian tumors is a suggested risk factor for germlineBRCA1/2 mutation status. We evaluated the presence of losses of selected microsatellite markers localized on chromosomes 17 and 13q in hereditary and sporadic ovarian tumors. 151 consecutive primary ovarian tumors (including 21 withBRCA1/2 mutations and(More)
BACKGROUND The clinical relevance of BRCA1/2 alterations in ovarian carcinoma patients is debatable. Our aim was to determine factors influencing the risk of recurrence and death in ovarian carcinoma patients with BRCA pathogenic and unclassified variant mutations. METHODS A consecutive series of 205 women with primary ovarian carcinoma were screened for(More)
BARD1 is the main binding partner of BRCA1 and is required for its stability and tumor-suppressor functions. In breast cancer and other epithelial cell carcinomas, alternatively spliced isoforms of BARD1 are highly upregulated and correlated with poor outcome. Recent data indicate that germline mutations of BARD1 may predispose to breast and/or ovarian(More)
The objective of this study was to determine the prevalence of BRCA1 and BRCA2 gene mutations in unselected ovarian cancer patients, and to analyse clinical and pathological features of ovarian cancer unclassified variant mutation carriers in comparison with BRCA1 pathogenic mutation carriers and sporadic cases. A consecutive sample of 205 women with(More)
