This hooks Claude into the NHGRI-EBI GWAS Catalog, letting you query genetic variant associations programmatically. You can look up SNPs by rs ID, search for variants linked to specific diseases or traits, pull p-values and effect sizes, or grab full summary statistics for polygenic risk scoring work. The skill covers both the web interface and REST API patterns, with working Python examples for common queries like finding all associations for a variant or filtering by genomic region. Honestly most useful if you're already doing genetic epidemiology or meta-analysis work and need to automate lookups instead of clicking around the web interface repeatedly. The catalog only includes genome-wide significant hits by default, so keep that threshold in mind.
