In Blood Cancer Discovery, Thibaud and colleagues report the incidence of pathogenic germline variants (PGV) in patients with multiple myeloma and that these PGVs are associated with DNA repair pathway genes, including BRCA1 and BRCA2. They find an association of patients with PGVs and previous family or personal history of cancer, and that these patients are diagnosed slightly earlier than those without PGVs. Patients with PGVs had a longer progression-free survival than those without PGVs when they received high-dose melphalan and autologous stem cell transplant, providing a therapeutic rationale for diagnostic germline testing in myeloma.

Association of Germline Pathogenic Variants in and Other DNA Damage Response Genes With Lung Cancer Risk Among Non-Hispanic Whites and African Americans.

Purpose: Although lung cancer is one of the most common malignancies, the underlying genetics regarding susceptibility remain poorly understood. We characterized the spectrum of pathogenic/likely pathogenic (P/LP) germline variants within DNA damage response (DDR) genes among lung cancer cases and controls in non-Hispanic Whites (NHWs) and African Americans (AAs).
Materials And Methods: Rare, germline variants in 67 DDR genes with evidence of pathogenicity were identified using the ClinVar database.

Rhabdoid tumours (RT) are an aggressive malignancy affecting <2-year-old infants, characterised by biallelic loss-of-function alterations in SWI/SNF-related BAF chromatin remodelling complex subunit B1 (SMARCB1) in nearly all cases. Germline SMARCB1 alterations are found in ~30% of patients and define the RT Predisposition Syndrome type 1 (RTPS1). Uveal melanoma (UVM), the most common primary intraocular cancer in adults, does not harbour SMARCB1 alterations.

Bone sarcomas, constituting less than 1% of malignant neoplasms across all age groups, are rare tumours possibly associated with genetic susceptibility syndromes. This review aims to provide recommendations for the detection of cancer predisposition syndromes associated with bone sarcomas and managing affected patients. Recommendations were formulated by a multidisciplinary working and reviewing group from GROUPOS and SFCE oncogenetic's group, including geneticists, oncologists, and radiologists.

Primordial germ cells (PGCs) are the first germline stem cells to emerge during early embryonic development and are essential for the propagation and survival of species. Genome editing creates mutagenesis possibilities in vivo, but the generation of precise mutations in PGCs is still challenging. Here, we report an optimized approach for highly efficient genome editing via introducing biallelic variations in early embryos in zebrafish.

Background: Germline pathogenic variants (gPVs) in the breast cancer susceptibility gene 1/2 (BRCA1/2) genes confer high-penetrance susceptibility to breast cancer (BC) and ovarian cancer (OC). Although most female BRCA carriers develop only a single BRCA-associated tumor in their lifetime, a smaller subpopulation is diagnosed with multiple primary tumors (MPTs). The genetic factors influencing this risk remain unclear.
