"Functional validation" means checking or testing something to ensure that it performs its intended purpose or function effectively and accurately. Full definition
For one thing, there's a pressing need for functional validation of statistical / genetic findings that come out of these studies. (massgenomics.org)
Even so, I'll do my best to summarize some of the options for functional validation, and ask you readers to comment with the things I've gotten wrong or forgotten. (massgenomics.org)
I believe that it is time to improve functional validation, so we can have better biological understanding and clinical application of genetic information. (ashg.org)
