4. Phenome map — where this gene is a genetic locus, vs. where MR exists
Top diseases by Open Targets association (of 1224 total). Associations are loci, not causal claims. The causal-status column is a four-state triage per pair: established (curated) = a curated clinical assertion exists (ClinGen/G2P/GEL/Orphanet/ClinVar — any validity level, MR adds little); exploratory rare-variant signal = ExWAS burden evidence without curation — a candidate NEW gene-disease relationship; common-variant locus = GWAS signal, classic pQTL-MR territory; multi-layer = burden+GWAS together, an allelic-series candidate (the strongest causal setup). Burden estimand is carrier-vs-noncarrier, not per-SD MR.

phenome — Top 30 of 1224 associated diseases by overall score. genetic_association aggregates GWAS common-variant AND rare-variant evidence. These are ASSOCIATIONS (loci), not causal claims.
chembl — ChEMBL target matched by text search on ‘APOB’ and resolved to ‘Apolipoprotein B-100’ — confirm this is the intended target.
clinvar — Pathogenic count is over the 30 record(s) retrieved, NOT over all 5193 ClinVar records for this gene; it is a sample, not a rate.
gwas_traits — Top 20 of 1083 traits by best p-value, aggregated from 2667 association rows. These are GWAS ASSOCIATIONS (loci), not causal claims; mapped genes at a locus are not necessarily the effector gene.
