Abstract
Development of hematologic malignancies is driven by mutations that may be somatic or germline. Availability of next-generation DNA sequencing technologies has facilitated the development of individualized diagnostic evaluations and tailored treatment strategies. Until now, such personalized medical approaches have largely centered on prognostic stratification and treatment strategies informed by acquired somatic mutations. The role of germline mutations in children and adults with hematologic malignancies was previously underappreciated. Diagnosis of an inherited predisposition to hematologic malignancy informs choice of therapy, risk of treatment-related complications, donor selection for hematopoietic stem cell transplantation, evaluation of comorbidities, and surveillance strategies to improve clinical outcomes. The recognition that patients with inherited hematologic malignancy syndromes may present without classic clinical stigmata or suspicious family history has led to increased reliance on genetic testing, which, in turn, has raised new diagnostic challenges. Genomic testing is a rapidly evolving field with an increasing number of choices for testing for the practicing clinician to navigate. This review will discuss general approaches to diagnosis and management of patients with germline predisposition to hematology malignancies and will consider applications and limitations of genomic testing in clinical practice.
