The PhenX Toolkit is a web-based catalog of high-priority measures related to complex diseases, phenotypic traits and environmental exposures.
[1] PhenX Toolkit's mission is to provide investigators with standard measurement protocols for use in genomic, epidemiologic, clinical and translational research.
[9][10][11] Such analyses compare independent findings to validate results or combine studies to increase sample size and statistical power.
[12][13] This increased power makes it possible to identify more subtle and complex associations such as gene-gene and gene-environment interactions.
[19] The Toolkit released six specialty collections of protocols to promote the use of CDEs for research on COVID-19 in October 2020.
