High- and Moderate-Risk Variants Among Breast Cancer Patients and Healthy Donors Enrolled in Multigene Panel Testing in a Population of Central Russia. (PubMed, Int J Mol Sci)

The BLM, NBN, and MUTYH genes did not demonstrate associations with BC risk. Finding deleterious mutations in BC patients is important for diagnosis and management; in controls, it opens up the possibility of prevention and early diagnostics.

Comprehensive Clinical Genetics, Molecular and Pathological Evaluation Efficiently Assist Diagnostics and Therapy Selection in Breast Cancer Patients with Hereditary Genetic Background. (PubMed, Int J Mol Sci)

Further immunohistochemistry analysis of breast tumour tissues helped clarify the causative role of these variants. Comprehensive clinical and molecular genetic evaluation is beneficial for the diagnosis and management of patients with P/LP variants in hereditary tumour-predisposing genes and can serve as a basis for effective therapy selection, such as PARP inhibitors or immunotherapy.

Validation and Performance of Quantitative BRCA1 and RAD51C Promoter Hypermethylation Testing in Breast and Ovarian Cancers. (PubMed, J Mol Diagn)

The results demonstrate that this test can accurately quantitate the level of promoter methylation at the BRCA1 and RAD51C genes using FFPE samples, even when the extracted DNA is extremely degraded or the input amount is limited. This test increases the precision of diagnostic tests aimed at identifying patients who are likely and unlikely to respond to PARP inhibitor therapy.

Investigating the effects of the ARG258HIS mutation on RAD51C in inherited Fanconi Anemia and cancer disease. (PubMed, J Biomol Struct Dyn)

These simulations highlighted alterations in conformational dynamics, the Free Energy Landscape (FEL), and intrinsic molecular motions induced by the mutation, suggesting structural destabilization that could disrupt its function. This observed destabilization in RAD51C due to mutations offers valuable insights that may serve as diagnostic markers for individuals carrying these mutations, particularly in Fanconi anemia.

Germline Variant Spectrum in Southern Italian High-Risk Hereditary Breast Cancer Patients: Insights from Multi-Gene Panel Testing. (PubMed, Curr Issues Mol Biol)

Variants of uncertain significance were detected in 20% of patients, emphasizing the ongoing challenge of variant interpretation in the era of multi-gene panel testing. These findings not only enhance our understanding of the genetic landscape of breast cancer in Southern Italy but also provide a foundation for developing more targeted, population-specific approaches to genetic testing and counseling, ultimately contributing to the advancement of precision medicine in oncology.

Hereditary breast and ovarian cancer genetic testing in unselected patients: example of private supplementation of public healthcare service. (PubMed, Fam Cancer)

Out of 177 patients referred to our center who underwent BRCA1/2 testing, 175 tested negative while two (1.1%) resulted carriers of pathogenic variants in BRCA2; 69 patients also underwent MGPT, and in four cases (5.8%) a pathogenic variant were found (two in ATM and one in CHEK2 and RAD51C, respectively). Overall, this private supplementation of territorial public healthcare system has made it possible to confirm the validity of regional criteria for genetic testing access (concordance: 98.9%), but also to identify carriers of pathogenic variants of BRCA1/2 that would have escaped regional protocol, to support the effectiveness of MGPT for the identification of rare cases (not BRCA) at mild/high risk, and to provide reassurance to women who were found to be non-carriers of pathogenic variants, who may benefit from a more accurate assessment of their risk.

Mismatch Repair (MMR) and Homologous Recombination (HR) Deficiency: Real-Life Applications of biomarkers for complementary approaches in Epithelial Ovarian Cancer (AIOM 2024)

HRD genomic instability tests and multigene panel assessments serve as synergistic tools in EOC clinical settings, proving essential for identifying patients likely to benefit from PARPi therapy. These tools also enhance the detection of HRR and MMR gene variants, aiding in preventive care. Further investigations into the genetic profiles of HRD-negative tumors are crucial for advancing cancer risk management and developing novel therapeutic avenues.

Elevated risks of contralateral breast cancer in carriers of PVs in high penetrance genes with DCIS confirmed the utility of testing for surgical decision-making.

High-resolution functional mapping of RAD51C by saturation genome editing. (PubMed, Cell)

We further explored our exhaustive functional map, revealing critical residues on the RAD51C structure and resolving variants found in cancer-segregating kindred. Furthermore, through interrogation of UK Biobank and a large multi-center ovarian cancer cohort, we find significant associations between SGE-depleted variants and cancer diagnoses.

Mechanism of BCDX2-mediated RAD51 nucleation on short ssDNA stretches and fork DNA. (PubMed, Nucleic Acids Res)

Moreover, while mutants defective in ssDNA binding retain the ability to bind branched DNA substrates, they still facilitate RAD51 loading onto reversed replication forks. Our study provides mechanistic insights into how the BCDX2 complex stimulates the formation of BRCA2-independent RAD51 filaments on short stretches of ssDNA present at ssDNA gaps or stalled replication forks, highlighting its role in genome maintenance and DNA repair.

Mutation Spectrum Comparison between Benign Breast Lesion Cohort, Unselected Cancer Cohort and High-Risk Breast Cancer Cohort. (PubMed, Cancers (Basel))

An unexpectedly high mutation rate of total 2% was found in the NC cohort but it was only 0.3% and 0.5% in the HR cohort and CC cohort, respectively. Our results show a clinical need to enhance genetic testing of unselected breast cancer patients to identify the high-risk patients.

Clinical Impact of Constitutional Genomic Testing on Current Breast Cancer Care. (PubMed, Clin Oncol (R Coll Radiol))

However, the lack of long-term clinical outcome data and incomplete understanding of variants, particularly for moderate-risk genes limits clinical application. In this review, we have summarized the key functions, risks, and prognosis of breast-cancer-predisposing genes listed in the National Health Service (NHS) England National Genomic Test Directory for inherited breast cancer and provide an update on current management implications including surgery, radiotherapy, systemic treatments, and post-treatment surveillance.
