bio-clinical-databases-polygenic-risk

bio-clinical-databases-polygenic-risk is a skill for Claude Code, Codex from PKU-YuanGroup/OpenAI4S. It costs 137 tokens per session (8,232 once invoked), scanned A, a copy of bio-clinical-databases-polygenic-risk, MIT.

A bioinformatics workflow for building polygenic risk scores, which estimate a person’s inherited likelihood of a trait or disease from many genetic variants.

In plain words
What is it for?
Use it to calculate, calibrate, validate, and report polygenic risk scores from genetic data using established statistical tools and reporting standards.
Why use it?
It helps account for ancestry and reference-panel differences when calculating and checking these scores, reducing misleading comparisons and poorly calibrated results.

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 A, and why

bio-clinical-databases-polygenic-risk scanned grade A with 0 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 (scripts/prsice2_workflow.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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 462 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: bigsnpr 1.12+ (LDpred2; Privé 2020), PRSice-2 2.3.5+, PRS-CS 1.0.0+ (Ge 2019), gctb 2.5+ (SBayesR/SBayesS/SBayesRC; Zheng 2024), LDAK 6.0+ (MegaPRS; Zhang 2021), pgsc_calc 2.0+ (nf-core; Lambert 2024), Hail 0.2.130+, numpy 1.26+, pandas 2.2+. No general FDA PRS guidance document exists as of May 2026; the operative regulatory text is the August 2025 Federal Register notice on Cancer Predisposition Risk Assessment Systems (Class II device with special controls).

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

  • Python: pip show <package> then help(module.function) to check signatures
  • R: packageVersion('<pkg>') then ?function_name
  • CLI: <tool> --version then <tool> --help to confirm flags

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying. The LDpred2-auto snp_ldpred2_auto() signature changed in bigsnpr 1.11+; pin allow_jump_sign = FALSE and shrink_corr = 0.95 explicitly.

Polygenic Risk Scores; Construction, Calibration, Reporting

'Compute a PRS for my cohort using these GWAS summary statistics' -> Match variants to target genotypes, choose method by data availability + trait architecture, derive LD-aware effect estimates, score, normalize by ancestry, transform to absolute risk.

  • CLI (recommended one-stop): pgsc_calc --target target.vcf --pgs_id PGS000001 (nf-core, Lambert 2024)
  • R (SOTA single-ancestry): bigsnpr::snp_ldpred2_auto() (Privé 2020)
  • CLI (multi-ancestry SOTA): PRS-CSx, PROSPER, MUSSEL, BridgePRS, JointPRS
  • CLI (SBayesRC with functional annotations): gctb --sbayes-rc --bfile target --gwas-summary sumstats.ma
  • CLI (legacy baseline): PRSice_linux (clumping + thresholding; still cited for some clinical scores)

Method Landscape: 2026 Operational Ranking

Method Approach Best for Fails when
SBayesRC (Zheng 2024 Nat Genet) Bayesian + 96 functional annotations EUR; sparse traits Sumstats LD-incoherent with reference; chain divergence (run --impute-summary first)
MegaPRS (Zhang 2021 Nat Commun) BLD-LDAK heritability model EUR; sparser traits Lacks GCTA-model assumptions; legacy GCTA pipelines
LDpred2-auto (Privé 2020) Bayesian + auto-tuning Polygenic EUR LD ref mismatch (s > 0.05); allow_jump_sign default True (must pin FALSE)
PRS-CS-auto (Ge 2019 Nat Commun) Continuous-shrinkage prior Polygenic EUR Sparse-trait architecture; HapMap3-restricted variants only
lassosum2 (Privé 2022) Penalized regression EUR alternative Highly polygenic (Bayesian methods better); requires tuning data
C+T (PRSice-2; Choi 2019) Clumping + thresholding Legacy clinical scores (PRS313) Highly polygenic; Bayesian methods dominate
PROSPER (Zhang 2024 Nat Commun) Ensemble penalized regression Multi-ancestry, AFR + others Single-ancestry; tuning set < 1000
MUSSEL (Jin 2024 Cell Genomics) Spike-slab + super-learner Multi-ancestry; admixed AFR Single-ancestry; lacks tuning data
JointPRS (Xu L et al 2025 Nat Commun 16:3841) Data-adaptive Bayesian Multi-ancestry; sumstats only Single-ancestry; very small target
PRS-CSx (Ruan 2022 Nat Genet) PRS-CS multi-ancestry extension Multi-ancestry with EUR + non-EUR sumstats Low causal-variant overlap across ancestries
BridgePRS (Hoggart 2024 Nat Genet) Ridge-bridge sharing Low-h^2 AFR / low causal overlap Standard scenarios (PROSPER/MUSSEL win)
PolyPred / PolyPred+ (Weissbrod 2022) BOLT-LMM + PolyFun-SuSIE Multi-ancestry; biobank-scale Small individual-level data; expensive

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.
