A striking 50% methylation of BRCA1 was identified in the benign sample cohort, which marks the significance of assessing the hypermethylation pattern to detect cancer at its early stages.
Given the substantial impact of BRCA1 mutations on cancer development risk in humans, a parallel loss of BRCA1 function in patient skeletal muscle cells would potentially result in implications for human health.
However, to the best of the authors' knowledge, rates of nonfounder BRCA1/2 mutations and mutations in cancer-associated genes other than BRCA1/2 among AJ are not known.
The risks of being a cisgender BRCA1/BRCA2 mutation carrier (BRCA1+/BRCA2+) are well documented, and recommendations to mitigate cancer risk in BRCA+ cisgender women are clear.
Furthermore, additional mechanisms apart from breast related cancer antigens 1 and 2 (<i>BRCA1/2</i>) mutations can also result in HR pathway alterations and consequently lead to a clinical benefit from PARP inhibitors.
We identify genetic variants of BRCA1-BARD1 in patients with cancer that exhibit poor protection of nascent strands but retain homologous recombination proficiency, thus defining domains of BRCA1-BARD1 that are required for fork protection and associated with cancer development.
We also discovered that cancer cells deficient in BRCA1 or its obligate partner BRCA1-Associated Protein-1 (BAP1) routinely repress miR223-3p to permit repair of stressed replication forks via aNHEJ.
The aim of this study was to compare patient-reported outcomes (PROs) of BRCA1/2 mutation carriers, either after bilateral prophylactic mastectomy (BPM) or during breast surveillance, to improve shared decision-making in their cancer risk management.
Two BRCA1 variants, R133H and E143K, and a RACK1 variant, K280E, associated with cancer, which weakened the BRCA1-RACK1 interaction, interfered with the centrosomal localization of BRCA1 and reduced centrosome amplification induced by overexpression of RACK1.
This includes significant advances in predicting individualized cancer risk based on hereditary cancer genetic testing, with the number of known cancer-predisposition genes extending well beyond BRCA1 and BRCA2.
<i>BRCA1/2</i> mutation carriers and non-carriers with elevated pedigree-based cancer risk were followed prospectively in a structured surveillance program between 2000 and 2017.
Biallelic BRCA1 mutations are regarded either embryonically lethal or to cause Fanconi anemia (FA), a genomic instability syndrome characterized by bone marrow failure, developmental abnormalities, and cancer predisposition.
Patients with non-mucinous epithelial tubo-ovarian cancers should be referred for genetic testing because approximately 15% will carry an inherited mutation in the <i>BRCA1 or BRCA2</i> cancer susceptibility genes.
We found that four E3 ubiquitin ligases (UHRF1, BRCA1, TRAIP and HLTF) and one regulator of ubiquitin E3 activity DCUN1D1 that were dramatically up-regulated in cancer were significantly associated with tumor metastasis and patient's poor prognosis both in two transcriptome data sets.
No studies evaluated the effectiveness of risk assessment, genetic counseling, and genetic testing in reducing incidence and mortality of BRCA1/2-related cancer.
We recommend BRCA1/2 testing for patients with family histories and personal histories of malignancy and genetic counseling for cancer in healthy people with high-risk family histories.
Increasing attention has been paid to the relevance of testing for men within BRCA1/2-positive families given that such testing may provide important information about their cancer risks, particularly for prostate cancer, and risks to their offspring.
