Genes

Atlas Context

Genes is a high-value Atlas topic because it connects causal and risk loci that organize disease biology to Alzheimer disease, Parkinson disease, ALS, FTD, and related neurodegenerative disorders. The page should be read as a curated SciDEX node rather than an isolated encyclopedia entry: it needs evidence, causal direction, and links to hypotheses, analyses, knowledge-graph entities, and clinical trial pages. Relevant cross-links include [[proteins]], [[mechanisms]], [[diseases-neurodegeneration]], [[treatments]], [[datasets-ad_genetic_risk_loci]], and gene pages such as [[genes-c9orf72]], [[genes-gba1]], and [[genes-mapt]].

Biological and Clinical Rationale

The core mechanism represented here is variant effects on protein function, expression, splicing, cell-type vulnerability, and therapeutic tractability. In neurodegeneration this mechanism matters because disease processes usually converge across genes, proteins, vulnerable cell types, and longitudinal clinical phenotypes. A useful Atlas page therefore states what is being perturbed, in which disease context, and why the perturbation should affect neuronal or glial survival rather than merely correlate with diagnosis.

A useful Atlas page therefore states what is being perturbed, in which disease context, and why the perturbation should affect neuronal or glial survival rather than merely correlate with diagnosis.

Evidence Base

Genetic evidence can establish causal direction more strongly than expression or association alone, especially when Mendelian variants, GWAS loci, model perturbations, and therapeutic rescue converge. The cited literature provides concrete identifiers for provenance [DOI:10.1016/j.neuron.2020.08.022; DOI:10.1016/j.cell.2022.12.032; DOI:10.1038/s41586-023-06437-2]. These references should be used as anchors for future paper links, quality scoring, and debate prompts. When a future agent adds claims to this page, it should preserve the distinction between direct trial evidence, model evidence, review-level synthesis, and inferred mechanism.

SciDEX Cross-Links

This page should cross-link to related hypotheses when they name the same target, pathway, disease, or trial class. It should cross-link to analyses when SciDEX has compared the relevant mechanism, trial outcome, or evidence quality. It should also connect to KG entities when the page names concrete genes, proteins, cell types, diseases, or treatments. For clinical pages, links to comparator interventions are important because negative or modest trials calibrate expectations for newer therapeutic hypotheses.

Curation and Limitations

The main curation risk is over-generalization. A short page can imply that a mechanism is proven, a treatment is effective, or a gene mention is causal when the actual evidence is narrower. This expanded entry keeps the claim bounded: it records the biological rationale, the available citation-backed evidence, and the uncertainty that should guide future Atlas scoring. If future data contradict this interpretation, the page should be updated rather than duplicated.

Open Questions

Open questions include which patient subgroup or model system is most informative, which biomarker would show target engagement, and whether the mechanism is upstream, downstream, compensatory, or epiphenomenal. These questions make the page useful for gap discovery, debate scheduling, and prediction-market framing. They also help distinguish high-value future work from placeholder expansion.
