PhenX Overview

The PhenX (consensus measures for Phenotypes and eXposures) Toolkit (https://www.phenxtoolkit.org) is a web-based catalog of recommended measurement protocols of phenotypes and exposures suitable for inclusion in genomic, clinical, and translational research studies with human participants.
The PhenX Toolkit supports consistent data collection by providing detailed protocols for collecting new data via different modes of administration. Current PhenX Data Collection Modes can be found here, https://www.phenxtoolkit.org/search.
For each protocol, the Toolkit provides detailed instructions (e.g., required training and equipment); features (e.g., Spanish language versions); and bioinformatics support (e.g., data dictionaries, REDCap compatible modules) which facilitate implementation of the protocols.
Studies that use PhenX protocols benefit from the ability to perform cross-study analyses to increase statistical power and to replicate results.
The use of PhenX protocols facilitates collaboration and data sharing, thus increasing the impact of individual studies over time.
