phexpo

"phexpo" is a specialized tool for exploring and analyzing bidirectional interactions between chemical compounds and human phenotypes. This innovative tool enhances exposome research by leveraging enrichment analyses to uncover complex relationships between environmental and genetic factors contributing to various phenotypes.

Key Features and Functionalities:

- Bidirectional Chemical-Phenotype Interactions: phexpo uniquely supports bidirectional analyses, enabling researchers to investigate relationships from chemicals to phenotypes and vice versa. This feature broadens the scope of exposome research by accommodating diverse investigational perspectives.

- Utilization of Curated Public Repositories: The tool integrates gene annotations from two curated public repositories: the Comparative Toxicogenomics Database and the Human Phenotype Ontology. This integration ensures the analyses are grounded in comprehensive and authoritative data sources.

- Versatile Application in Case Studies: phexpo has been applied in three distinct case studies, demonstrating its versatility. These include linking individual chemicals (such as the drug warfarin and the industrial chemical chloroform) with specific phenotypes, associating individual phenotypes (like left ventricular dysfunction) with chemicals, and correlating multiple phenotypes (encompassing conditions like polycystic ovary syndrome) with chemicals.
