Abstract

PURPOSE: To undertake the first end-to-end cost-effectiveness analysis of exome sequencing (ES) in rare disease diagnosis. METHODS: A cohort of 80 infants who underwent ES and usual diagnostic care in parallel were used to model incremental cost and health outcomes (quality adjusted life-years, QALYs) attributable to ES diagnosis over a 20-year horizon. Three models were developed: (1) outcomes in patients only, (2) outcomes in patients and first-degree relatives as a result of cascade testing, and (3) outcomes in patients and first-degree relatives including parental reproductive outcomes. RESULTS: When the directly observed cost and health outcomes of the cohort participants were projected..
