Screening yields vary across reported cohorts

  • 19% and 51.1%Among 94 participants with vendor data, 19% sought confirmatory testing and 51.1% declined it during the initial counseling session.[1]

How screening results differ across settings

Reported yields range from a single actionable finding among 12 healthy people screened generally to actionable variants in 3.6% of a community-ascertained cohort; these figures come from different cohorts and are not a head-to-head test comparison.[2] [3]

Later discussion identifies gaps in understanding penetrance, variation in risk by ethnicity or lifestyle, and limited representation of variant spectra across diverse populations as constraints on precise risk estimates.[4]

What remains unresolved about genomic screening

  • How well do screening interpretations predict actual disease risk when penetrance is uncertain and false-positive interpretations are possible?[4] [5]
  • What health outcomes follow over time when screening identifies people who may not have been found through existing testing guidelines?[3] [6]
