bio-clinical-databases-polygenic-risk SKILL.md skillA
bio-clinical-databases-polygenic-risk from fridrichmethod/awesome-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Calculate polygenic risk scores using PRSice-2, LDpred2, or PRS-CS from GWAS summary statistics. Use when predicting disease risk from genome-wide genetic variants.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Version Compatibility
Reference examples tested with: LDpred2 1.14+, PRSice-2 2.3+, numpy 1.26+, scipy 1.12+
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` to verify parameters
- 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.
# Polygenic Risk Scores
**"Calculate polygenic risk scores for my cohort"** → Compute genome-wide risk scores from GWAS summary statistics and individual genotypes to predict disease susceptibility.
- CLI: `PRSice_linux --base gwas.txt --target genotypes --out prs_results`
- R: `bigsnpr::snp_ldpred2_auto()` for LDpred2 Bayesian PRS
## PRSice-2 Workflow
**Goal:** Calculate polygenic risk scores from GWAS summary statistics using clumping and thresholding.
**Approach:** Run PRSice-2 with GWAS summary stats and target genotypes, applying LD clumping and multiple p-value thresholds.

How to install
mdr add fridrichmethod/awesome-skills/bio-clinical-databases-polygenic-risk@sha256:2f2080aa857f1414The line at the top of this page pins the label git:20260517.81511a7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
