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

20 association rows across 11 traits (19 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 408 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
Neonatal acute respiratory distress with surfactant metabolism deficiency 0.82 established (curated) no MR -> candidate analysis
surfactant metabolism dysfunction, pulmonary, 1 0.839 established (curated) no MR -> candidate analysis
Congenital pulmonary alveolar proteinosis 0.608 established (curated) no MR -> candidate analysis
hereditary pulmonary alveolar proteinosis 0.858 established (curated) no MR -> candidate analysis
Moderate albuminuria 0.279 common-variant locus no MR -> candidate analysis
alcohol drinking 0.261 common-variant locus no MR -> candidate analysis

Of the 6 rows above, 6 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.
