GenPhenia

Step 1

Clinical setting

We begin with a real clinical scenario.

The case

A 16-year-old boy with delayed puberty and low reproductive hormone signals.

Benchmark

On the Mayo Clinic rare-disease dataset, GenPhenia outperforms Phen2Gene, PCAN, CADA, and PPAR (Mayo Clinic) across Top-1, Top-10, and Top-50 retrieval cutoffs.

This step can repeat until the phenotype is informative enough.

Step 3

As you scroll, GenPhenia replays the path so far: clinical description, HPO encoding, differential refinement, and gene prioritization.

Step 4

Review the clinical record after the model run.
