2. pQTL instrument availability (Tier-B probe)

No prot-* pQTL GWAS dataset found for this protein (matched by UniProt accession and symbol).

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

136 association rows across 65 traits (131 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 258 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
Abnormality of the skeletal system 0.887 common-variant locus no MR -> candidate analysis
smoking behavior 0.607 common-variant locus no MR -> candidate analysis
Varicose veins 0.594 common-variant locus MR: beta=0.154, p=0.0293 (cis)
ovarian cancer 0.445 established (curated) MR: beta=0.242, p=1.82e-04 (cis)
pulmonary tuberculosis 0.511 common-variant locus no MR -> candidate analysis
gastroesophageal reflux disease 0.443 common-variant locus no MR -> candidate analysis

chronic obstructive pulmonary disease 0.294 common-variant locus no MR -> candidate analysis
obesity disorder 0.035 common-variant locus no MR -> candidate analysis

Of the 10 rows above, 8 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.
