Frequently asked questions
AI-generated answers based on this skill's SKILL.md and metadata
How does tooluniverse-gwas-study-explorer compare GWAS studies for the same trait?
tooluniverse-gwas-study-explorer systematically compares genome-wide association studies by integrating GWAS Catalog and Open Targets Genetics data. It aggregates effect sizes across multiple studies for any trait, enabling you to assess replication success across cohorts and identify which loci replicate consistently versus appear in single studies.
How to check if GWAS findings replicate using this tool?
tooluniverse-gwas-study-explorer evaluates GWAS reproducibility by comparing effect sizes and significance across independent cohorts. It detects heterogeneity from population and design differences, assesses study quality by sample size and ancestry diversity, and distinguishes replicated loci from novel findings to determine which associations hold across populations.
Can tooluniverse-gwas-study-explorer perform meta-analysis across GWAS cohorts?
Yes. tooluniverse-gwas-study-explorer aggregates effect sizes from multiple GWAS studies through meta-analysis, enabling you to combine results across cohorts. It calculates heterogeneity metrics and detects sources of variation from ancestry and study design, supporting both discovery and replication workflows.
What does tooluniverse-gwas-study-explorer reveal about ancestry-specific genetic signals?
tooluniverse-gwas-study-explorer identifies replicated loci and assesses ancestry-specific genetic signals by comparing GWAS results across populations. It evaluates genetic risk score transferability and detects population stratification effects, helping you understand whether associations are universal or ancestry-specific.
How does this tool investigate heterogeneity in genome-wide association studies?
tooluniverse-gwas-study-explorer investigates sources of heterogeneity by analyzing effect size variation across studies. It quantifies I-squared heterogeneity metrics and traces variation to population differences, study design factors, and sample composition, enabling you to understand why associations may differ between cohorts.

Tooluniverse Phewas inverts the GWAS paradigm by fixing a variant or gene and scanning the entire phenome across four ancestry-matched biobanks plus exome-wide gene-burden data. Query a single rsID to discover all associated phenotypes, compare effect directions and allele frequencies across populations, and distinguish robust replicated signals from ancestry-specific or underpowered findings.
Query the 1000 Genomes Project (IGSR) to find populations and samples stratified by superpopulation codes, explore data collections, and retrieve population-specific allele frequencies. Combine population metadata with GWAS tools to analyze ancestry-dependent genetic associations and identify population-specific effects.
Identify genes associated with diseases and traits by querying GWAS Catalog and Open Targets Genetics data. This skill ranks candidate genes using locus-to-gene scores that combine eQTL, chromatin interaction, and distance evidence—moving beyond simple nearest-gene approaches. Results include p-values, replication counts, and confidence levels to guide target prioritization for drug discovery and functional validation.
This skill applies Bayesian fine-mapping methods to pinpoint causal variants within GWAS-associated regions, moving beyond the lead SNP to compute posterior probabilities for each variant in a credible set. It integrates locus-to-gene predictions and functional annotations to link variants to their target genes, helping researchers distinguish true causal effects from linkage disequilibrium artifacts.
Access the NHGRI-EBI GWAS Catalog to find genetic variant associations with diseases and traits. Search by rs ID, phenotype, gene, or genomic region to retrieve p-values, effect sizes, and study metadata for epidemiological research and risk score development.
Access the NHGRI-EBI GWAS Catalog REST API to search published genome-wide association studies and retrieve SNP-trait associations, variants, and summary statistics. Query by disease trait, PubMed ID, variant, or chromosomal region to explore genetic architecture, check pleiotropy, and build polygenic risk score candidates. No authentication required.
