    RAD51 Paralogs and RAD51 Paralog Complexes BCDX2 and CX3 Interact with BRCA2. (PubMed, bioRxiv)
    Furthermore, the interaction with RAD51B is dependent upon an FxxA motif located on a surface exposed region of the CTD. Our study has identified novel interactions between the RAD51 paralogs and BRCA2 and further demonstrated that a previously unrecognized FxxA motif located within a mobile element of RAD51B is critical for the interaction.

    Diet induced mitochondrial DNA replication instability in Rad51c mutant mice drives sex-bias in anemia of inflammation. (PubMed, bioRxiv)
    Consequently, treatment of male Rad51c mutant mice with estrogen or mitochondrial antioxidants suppresses the inflammation-induced anemia. Collectively, this study uncovers estrogen-responsive mtDNA replication instability as a cause for sex-specific inflammatory responses and molecular driver for AI.

    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.

    Primary fallopian tube cancer followed by primary breast cancer in RAD51C mutation carrier treated with niraparib as first line maintenance therapy: a case report. (PubMed, Hered Cancer Clin Pract)
    The patient received three cycles of neoadjuvant chemotherapy with paclitaxel and carboplatin and achieved a complete response. The metachronous breast cancer in this case may be the first report of second primary cancer in fallopian tube cancer patient harboring a RAD51C mutation during niraparib treatment. Further studies are required to determine optimal treatment.

    Real-world homologous recombination repair mutation (HRRm) testing patterns in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with olaparib in the United States. (ASCO-GU 2024)
    Pts with confirmed mCRPC diagnosis, age ≥21 years, treated with olaparib monotherapy after exposure to abiraterone or enzalutamide, and with positive HRRm status were included. This real-world analysis highlights the need for earlier HRRm testing in pts with mCRPC to allow for optimal timing of novel treatment options that have shown efficacy in a biomarker-selected population. Most pts in this study were tested and diagnosed with HRRm many months after mCRPC diagnosis, at which point they had high levels of bone metastasis, multiple sites of distant metastases, and opioid use at the initiation of olaparib treatment. HRR testing in pts before or at the time of mCRPC would allow for olaparib therapy earlier in the disease course.

    BRCA2, ATM and CDK12 were the most prevalent single gene mutations and clinical benefit was observed with O + A. Other single gene mutations were rare, limiting interpretation. The greatest treatment benefit was observed in pts with BRCA mutations. Clinical trial information: NCT03732820.NR, not reached; BRIP1, RAD51B, RAD51D n=1; CHEK1, RAD51C n=0.

    The role of DNA repair genes mutational status in prostate cancer treatment with androgen signaling blockade (EMUC 2023)
    Probably, the data obtained on the worst efficacy of enzalutamide after docetaxel in patients with mutations in  HRR genes can be attributed to the biological features of the influence of therapy methods on the course of the disease. In clinical practice, it is advisable to take into account the fact of the influence of previous treatment on the effectiveness of antiandrogenic therapy in choosing the sequence of treatment methods.

    Unique molecular signatures of germline mutations in low expression of human epidermal growth factor receptor 2 (HER2) breast cancer (SABCS 2023)
    HER2-low BC patients have distinct germline mutational signatures and differential clinical outcomes under neoadjuvant systemic therapy. These results have provided additional evidence that HER2-low patients comprise a fourth subtype of BC that needs to be accounted for separately in terms of clinical treatment and outcome reporting.

    The MAGIC study: Universal whole genome tumour and germline sequencing of newly diagnosed breast cancer identifies a high proportion of ER+ BRCA-like tumours (SABCS 2023)
    Tumour sequencing identified three times as many cases that might be eligible for HR repair defect targeted therapy than germline testing alone (16% versus 5.2%). Unlike a previous study (Ann Oncol., 2019 30:1071-1079), the majority of the BRCA-like BCs were ER+ with no evidence of a VUS in a known HBC gene suggesting these are driven by novel germline or somatic mutations in genes involved in DNA HR repair.
