        "note": "The GWAS Catalog is the NHGRI-EBI curated collection of published human genome-wide association studies — which genetic variants are statistically associated with which traits and diseases. /v1/snp?id=rs7329174 = a SNP's annotation: functional class, genomic location(s) (chromosome, position), mapped genes and how many associations reference it; /v1/associations?id=rs7329174 = every trait association reported for that SNP — the trait(s), p-value, effect size (odds ratio or beta), risk allele and frequency and author-reported genes; /v1/study?id=GCST000028 = a study's metadata: trait, sample sizes, SNP count, ancestries, genotyping technologies and the publication (PubMed id, author, title, journal, date). rsIDs look like rs7329174; study accessions like GCST000028 (get one from /v1/associations). Data from the NHGRI-EBI GWAS Catalog (EMBL-EBI, public). A published genetic-association evidence base — distinct from population allele frequencies (gnomAD), clinical variant interpretation (ClinVar) and genome annotation (Ensembl). Ideal for genomics, bioinformatics, statistical-genetics and research tooling.",
