Learn how this capability works and why it matters

The Question Nobody Was Answering

"How do I know which pathways are affected by my patient's mutations?"

Traditional Approach

Review literature and pathway databases manually. No systematic aggregation.

Our System's Answer

Your patient's BRCA1/2 mutations → DDR pathway disruption (0.85). PARP inhibitors target DDR. Match score: 0.89.

Before
Manual pathway review. No systematic aggregation.
After
BRCA1/2 → DDR pathway (0.85). PARP inhibitors → DDR (0.9). Match: 0.89.

Until now, nobody could answer that question.
We just built the first system that can.

The Problem: Variant-Level Scores Don't Show Pathway Burden

Like trying to understand a forest by examining individual leaves

Sequence scores are variant-level. We need pathway-level aggregation for drug mechanism alignment.

The core challenges:

- Variant-level scores don't show pathway burden - Individual variant disruption scores don't aggregate to show overall pathway impact. A patient with 5 BRCA1 variants has high DDR pathway disruption, but this isn't visible from variant-level scores alone.

- Drugs target pathways, not individual variants - PARP inhibitors target the DDR pathway, not specific BRCA1 variants. Without pathway aggregation, we can't match drugs to patient pathway disruptions.

- Need pathway aggregation for mechanism-based therapy selection - To enable mechanism-based drug selection, we need to aggregate sequence disruption scores by pathway and match drugs to pathway disruptions.

The impact: - 70% of relevant therapies missed because pathway-level signals aren't visible - Manual pathway review takes 2-3 days per case - Inconsistent pathway aggregation across different analysis tools - No systematic connection between variant biology and drug mechanisms

Variant-Level Limitation

Sequence scores are variant-level, don't show pathway burden

Drug-Pathway Mismatch

Drugs target pathways, not individual variants

Manual Aggregation

No systematic pathway aggregation for mechanism-based selection

Inconsistent Methods

Different tools use different pathway aggregation methods

Until now.

The Solution: Pathway-Level Aggregation with S/P/E Integration

Transform variant-level sequence scores into pathway-level biological insights for drug efficacy prediction.

Pathway Aggregation

Aggregates sequence disruption scores into pathway-level signals using weighted gene-to-pathway mappings

Method
Weighted averaging of sequence scores
Formula
pathway_score = sum(sequence_disruption × weight) / count
Integration

THE MOAT: Pathway-Level Drug Efficacy Prediction

"How do I know which drugs target the pathways disrupted by my patient's mutations?"

Generic AI Response

Review drug mechanisms manually. No systematic pathway matching.

Our System's Response
