3. GWAS Catalog results — traits with signal at this locus

13 association rows across 9 traits (13 genome-wide significant rows). Associations are loci, not causal claims; the mapped gene at a locus is not necessarily the effector gene.

4. Phenome map — where this gene is a genetic locus, vs. where MR exists

Top diseases by Open Targets association (of 232 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.

Disease genetic assoc. burden (ExWAS) causal status MR status
immunodeficiency due to ficolin3 deficiency 0.607 established (curated) no MR -> candidate analysis
rheumatic heart disease 0.35 established (curated) no MR -> candidate analysis
microcephaly 0.182 established (curated) no MR -> candidate analysis
gout 0.127 common-variant locus no MR -> candidate analysis
hypertensive disorder 0.091 common-variant locus no MR -> candidate analysis

Of the 5 rows above, 5 have no MR estimate in this resource. Across all retrieved diseases for this gene: 0 exploratory rare-variant signal(s), 0 multi-layer (allelic-series candidate) pair(s). Final triage still belongs to a statistical geneticist.
