bio-causal-genomics-effector-gene-prioritization

bio-causal-genomics-effector-gene-prioritization is a skill for Claude Code, Codex from GPTomics/bioSkills. It costs 228 tokens per session (10,866 once invoked), scanned B, original, MIT.

A workflow for ranking genes that may be responsible for the effects of GWAS-implicated regions. It combines evidence from variant-to-gene links, gene-level association tests, gene regulation, and other biological data.

In plain words
What is it for?
Use it to score and compare candidate genes near associated variants, integrate results from tools such as MAGMA and Open Targets, and choose genes for biological follow-up.
Why use it?
A GWAS usually points to a region rather than a specific gene, and the nearest gene is not always the relevant one. Combining several evidence sources gives a structured way to prioritize candidate effector genes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

bio-causal-genomics-effector-gene-prioritization scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (examples/magma_genebased.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

The opening of the file, as written. The whole thing — 422 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: MAGMA 1.10+ (cncr.nl/research/magma), FUMA web platform v1.6+ (fuma.ctglab.nl), Open Targets Genetics API (REST + GraphQL, June 2024 release), PoPS (head of FinucaneLab/pops, 2024), cS2G pre-computed scores (Zenodo record 7754032, Gazal 2022), ABC-Enhancer-Gene-Prediction 0.2.2+, ENCODE-rE2G v1.0+ (Gschwind 2023 preprint), DEPICT v1 rel194, INQUISIT (Fachal 2020 supplementary), Python 3.9-3.11, R 4.3+, PLINK 1.9 + PLINK 2.0.

Before using code patterns, verify installed versions match. If versions differ:

  • CLI: magma --help to confirm gene-window, gene-annot, and gene-set flag names
  • Python: pip show gentropy; introspect endpoints at api.platform.opentargets.org/api/v4/graphql
  • R: packageVersion('coloc') etc. for upstream evidence integration

If a script throws an error about an argument that has moved (e.g. an Open Targets endpoint renamed during a release) or a model file schema change, introspect the installed tool and adapt rather than retrying. Open Targets Genetics deprecated the standalone Genetics Portal in 2024 in favour of the integrated platform; verify endpoint URLs at the time of use.

Effector Gene Prioritization

"Which gene at this GWAS locus is actually the causal mediator?" -> Integrate fine-mapping, colocalization, chromatin-based enhancer-gene predictions, distance, and gene-similarity priors into a per-locus per-gene confidence score, then require concordance across multiple orthogonal evidence streams before nominating a causal effector. Effector gene prioritization is the bridge between statistical fine-mapping (variant level) and biological hypothesis (gene level); it is the most failure-prone step in GWAS-to-target pipelines because the nearest-gene assumption is wrong roughly 30-50% of the time at well-studied loci.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
