Automate Gestational Phenotype GWAS Analysis with Hail and LlamaIndex

Genome-wide association studies across gestational phenotypes reveal context-specific maternal-fetal genetic risk factors. Build a queryable GWAS synthesis agent using Hail and LlamaIndex to process summary statistics across 50 maternal traits and index context-specific variant locus associations.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

significance_filter_test

Ensures outputted p-value satisfies the significance threshold.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

locus_identification_accuracy

Accuracy in mapping correct lead SNP per phenotype. • target: 0.95 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Process large-scale GWAS summary statistics using PySpark/Hail matrix tables.

  • Index locus-level p-value and effect size signals using LlamaIndex.

  • Identify context-specific genetic effects distinct to specific gestational trimesters.
