Family health history (FHH) information is well established as a basis for assessing a patient's personal disease risk, but is underutilized for diagnosis and making medical recommendations. Epidemiological and genetic information have heightened the value of FHH to an individual's health. This has motivated the development of new FHH collection tools and strategies for family members, but will require greater awareness and knowledge by both patients and practitioners. FHH will be increasingly important as genomic data become a mainstay of medical diagnostics, since in many cases, a medically important FHH results from lineage-specific genetic variants. The impact of complementary FHH and genomic information will drive the pursuit of personalized and precise targeting of treatments and interventions aimed at maintaining patient health.
