A Role for Germline Variants in Multiple Myeloma?

Abstract:
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. See related article by Thibaud et al., p. 428.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
