    Integrating breast tumour homologous recombination deficiency status to aid germline BRCA1 and BRCA2 variant classification. (PubMed, EBioMedicine)
    Analysis across multiple tumour whole-genome sequencing datasets has shown that HR status prediction algorithms can separate profiles for BRCA1 and BRCA2 pathogenic variants and provide further evidence at increased weight to aid in the classification of germline BRCA1 and BRCA2 variants. Tumour sequencing offers a promising strategy for reducing the uncertainty in germline variant interpretation.

    BCDX2-CX3 and DX2-CX3 complexes assemble and stabilize RAD51 filaments. (PubMed, Nature)
    These distinct assemblies are differentially regulated by ATPase activity, defining a dynamic BCDX2-CX3 "loader" and a stable DX2-CX3 "anchor" that provide functional modularity to the HR machinery. This work provides a unifying mechanism for human RAD51 paralog function and delivers an atomic blueprint for interpreting disease-causing mutations.

    Whole Exome Sequencing Revealed Rare Variants in BRCA2, RAD51D, FANGC, CYP24A1 Genes in Breast/Ovarian Cancer Patients from a Small Buryat Ethnic Group. (PubMed, Asian Pac J Cancer Prev)
    For the first time, rare germinal variants in the BRCA2, RAD51D, FANGC, CYP24A1 genes were detected in a small Buryat ethnic group. Our data are consistent with existing data showing that variants in the RAD51D gene may be involved in the pathogenesis of breast/ovarian cancer. We also showed that the Mongolic-speaking Buryat populations exhibited strong genetic resemblance to those of Chinese.
