Approach Toward Germline Predisposition Syndromes in Patients with Hematologic Malignancies

AbstractPurpose of ReviewHematologic malignancies were previously thought to be primarily sporadic cancers without germline predispositions. However, over the last two decades, with the widespread use of next generation sequencing (NGS), there have been several genes  have been identified that carry a risk of inheriting hematologic malignancies. Identification of individuals with hereditary hematologic malignancies (HHM) involves a high index of suspicion and careful attention to family history, clinical features, and variant allele frequency on somatic NGS pan els.Recent FindingsOver the last several years, many genetic predisposition syndromes have been recognized to have unique features with both hematologic and non-hematologic co-morbidities. Multidisciplinary evaluation, including genetic counseling, is critical to optimizing diagnostic testing of individuals and at-risk family members. Prompt recognition of affected patients is imperative not only for personalized surveillance strategies but also for proper donor selection for those undergoing stem cell transplantation to avoid familial donors who also may share the same germline mutation.SummaryHerein, we describe our approach to recognizing patients suspected to carry a germline predisposition to hematologic malignancies and evaluation within a hereditary hematologic malignancies clinic (HHMC).
