RTI International has released a new version of its free online “toolkit” designed to help genetics researchers consistently measure and report physical traits and environmental exposures.

Called PhenX, a name RTI derived from “phenotype” and “exposures,” the guide provides nearly 300 standard measures and protocols across 21 different research areas. The measures are intended for use in genome-wide association and other large-scale research studies, RTI said.

The goal is to bolster efforts to compare data from multiple studies..

The toolkit, available at its own website, is funded by the National Institutes of Health’s National Human Genome Research Institute and has received support from the NIH Office of Behavioral and Social Sciences Research.

The measures and protocols in the toolkit were selected over the past three years by working groups of more than 200 scientists from diverse scientific and health disciplines, including many participants from NIH institutes and centers, using a consensus-based process.

The toolkit allows investigators to expand a study beyond the primary research focus by adding PhenX measures to the study design.
