RNF43 + GNAS
RNF43 and GNAS co-occurrence in pancreatic cancer (MSK-CHORD)
DataMSK-CHORD (2024) · Pancreatic cancer · 3,065 tumours · both altered in 10 (2.5 expected if independent)
This cohort pools pancreatic adenocarcinoma with pancreatic neuroendocrine tumours, so a pattern here can reflect the mix of tumour types rather than biology within one of them.
Strengthened. Significant, with a real effect in a consistent direction, and it still holds when tumours are compared only within the same tumour type (and within the same molecular subtype, wherever this cancer's subtypes are known in the data). No artifact check failed.
A well-studied pair (385 papers): on the map it is known biology, a positive control rather than an overlooked discovery.
Not called novel: a PubTator3 search finds 46 papers naming both RNF43 and GNAS in pancreatic cancer in the title or abstract. See the PubTator3 search.
Signal (x) is the corrected significance on the map's scale, discounted from 19% to 8% because the cohort-composition confound is not yet controlled. Efficacy (y) is credibility times actionability.
These genes are altered together more often than chance would predict.

Substantial evidence. Below the α=0.05 reject threshold (e≥20). Unlike a single-look p, this stays valid under the engine's continuous re-testing.
Molecular-subtype certification is unresolved. Recorded lineage only. Within-lineage molecular subtype remains unresolved. The association remains visible, but does not qualify as a subtype-controlled discovery.
The two axes are variables: signal (x) and efficacy (y = credibility × actionability). A point high on both lands in the frontier (top-right). A strong signal with low credibility sits low and to the right: statistically strong, not worth pursuing.
A language model wrote this from the evidence listed below. It is annotation: the engine's verdict above comes only from the measured statistics, never from this text.
The RNF43–GNAS co-occurrence in pancreatic cancer is most likely driven by unresolved molecular-subtype or lineage composition: subtypes enriched for both alterations may create a population-level association without the alterations cooperating within the same tumour. This explanation is testable by asking whether the association attenuates after subtype adjustment.
- 1The association is a credible population-level signal: it remains significant after burden adjustment and multiple-testing correction, with a within-stratum log2 odds ratio of 2.3 (95% CI 1.3–3.3) across 10 double-altered tumours. These statistics support co-occurrence, not a within-tumour interaction.E1E18
- 2Subtype composition is the leading explanation because only lineage is recorded and molecular subtype remains unresolved; the measured heterogeneity test does not rule out subtype confounding. The same-pair Cybergenic finding explicitly favored molecular-subtype composition, so this lead CONVERGES with it.E2E15
- 3The supplied IPMN review abstracts provide context on pancreatic precancerous lesions but do not study or establish a specific RNF43–GNAS relationship. Thus they do not support a within-tumour mechanism; broad pair co-mentions in the literature are not mechanistic evidence.E8E9E10
- 4The result has not replicated across independent patient sources, so a cohort-specific effect or winner's-curse/data artifact is the strongest competing explanation. The other cited corpus findings do not directly contradict the same-pair result or resolve its cause.E3E14E16E17
Test an independent pancreatic cancer cohort with molecular-subtype annotations using a subtype-adjusted logistic model and subtype-stratified co-occurrence estimates; attenuation of the RNF43–GNAS association after adjustment would support subtype composition. To earn a within-tumour cooperation claim, first use single-cell or clonal genotyping to establish co-occurrence in the same tumour cells, then test functional co-dependency in an appropriate model.
This is a conservative ranking, not a demonstrated cause: (1) unresolved molecular-subtype/lineage composition is most likely; (2) cohort-specific biology or a scanning-related artifact/winner's curse is a substantial alternative given the lack of cross-source replication; (3) a shared upstream driver is possible but is not identified by the evidence; (4) deterministic co-amplification is unsupported here because no shared amplicon or copy-number evidence is supplied; and (5) genuine within-tumour cooperation is least justified without a paper studying this pair and direct clonal or functional evidence. The supplied paper abstracts do not study the pair, which leaves the proposed within-tumour mechanism under-explored rather than supporting it (E3, E8–E10).
Weakest link: The evidence establishes a cohort-specific co-occurrence but provides no subtype measurements or adjusted analysis showing that subtype composition explains it; the lineage-adjusted association remains substantial.
Significant (after FDR correction) in one independent source of this tumour type so far. The engine records where a pattern is significant, not every source that could test it, so this calls for caution: a pattern selected from many tests tends to overstate its effect. It does not count against the pattern.
- E1In Pancreatic cancer (MSK-CHORD 2024), RNF43 and GNAS are co-occurring: burden-aware DISCOVER p = 3.6e-5 (a test that accounts for each tumor's overall alteration burden, so co-occurrence is not inflated by unstable tumors carrying more of everything), Benjamini-Hochberg FDR q = 7.8e-3, within-stratum (Mantel-Haenszel) log2 odds ratio 2.3 (95% CI 1.3 to 3.3), 10 tumors carry both alterations.cBioPortal / MSK-CHORD (2024)
- E2The co-occurrence was tested at adjusted FDR q=7.8e-3 with 100% annotation coverage. Recorded lineage only. Within-lineage molecular subtype remains unresolved. The measured heterogeneity test did not reject a common effect; this does not prove homogeneity. This control alone establishes neither a mechanism nor novelty.cBioPortal / MSK-CHORD (2024), scoped DISCOVER control
- E3This co-occurrence is FDR-significant in only 1 independent patient source so far and does NOT recur across sources, so it could be cohort-specific biology or a winner's-curse artifact of scanning many cohorts. Treat confidence accordingly.cBioPortal (cross-cohort)
- E4RNF43 expression is higher in tumor than matched GTEx+adjacent normal tissue: log2 fold change 1.21 (7.4 vs 3.2 TPM, n=179 tumor / 171 normal). A >2x shift is a real expression-level signal on top of the DNA alteration.UCSC Xena (tumor vs GTEx normal)

- E18Significance is FDR-corrected: Benjamini-Hochberg q = 7.8e-3 across 1711 gene pairs tested in this cohort, so this pair SURVIVES multiple-testing correction (q ≤ 0.05). The q, not the nominal p, is the honest signal strength.Cybergenic method
Model-written annotation, not a finding. The statistics it cites are real and are shown above; the argument connecting them is a hypothesis that needs wet-lab or clinical validation before it means anything.
