Whole genome sequencing (WGS) can be used to predict future disease risk or inform treatment. Current guidelines suggest only reporting variants that are clinically actionable. Reporting incidental or non-actionable findings could generate anxiety and unnecessary medical tests, but patients could miss valuable information if not reported. Over-treatment may occur by acting on findings prematurely, potentially causing harm and unnecessary resource use. We measure the value of WGS information using contingent valuation methods.
