Solution Overview
Problem
Current guidelines for identifying pathogenic mutations, such as ACMG-AMP and Sherloc rules, are imprecise and require human judgment, making full automation of pathogenic mutation classification challenging due to unclear definitions and inconsistent interpretations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated classification methods are implemented, then productivity and automation extent are improved, but classification precision and reliability deteriorate due to lack of human judgment
Solution Approach 1:
The classification system segments the pathogenic mutation assessment into five independent scoring dimensions: population frequency score, variant type score, clinical score, functional score, and inheritance pattern score. Each dimension is evaluated separately by dedicated modules, allowing automated processing while maintaining comprehensive assessment coverage. This segmentation enables parallel computation and improves efficiency without sacrificing classification precision.
Solution Approach 2:
The system merges multiple data sources and scoring criteria into a unified pathogenic score calculation framework. Population database results, variant type predictions, clinical database information, functional predictions, and inheritance pattern analyses are integrated through a weighted scoring system. This merging approach consolidates diverse information sources into a single comprehensive assessment, achieving both automation and precision.
2Reliability
If comprehensive databases and multiple scoring criteria are used, then classification reliability is improved, but device complexity and computational requirements worsen
Solution Approach 1:
The complex classification system is divided into five modular scoring components, each handling a specific aspect of pathogenic assessment. The population module queries population databases independently, the variant type module analyzes sequence variations separately, the clinical module evaluates clinical database matches independently, the functional module assesses functional predictions separately, and the inheritance pattern module analyzes transmission patterns independently. This modular segmentation reduces system complexity while maintaining comprehensive reliability.
Solution Approach 2:
The scoring framework uses a universal weighted sum calculation method that can accommodate multiple data sources and criteria types. The same computational approach (weighted scoring) is applied across all five dimensions, providing a consistent and manageable processing mechanism. This universal method simplifies the handling of diverse databases and criteria while maintaining classification reliability.
3Measurement precision
If manual interpretation is required, then classification precision is improved, but productivity and automation extent worsen
Solution Approach 1:
The system implements self-service automation where the classification algorithm independently queries population databases, analyzes variant types, searches clinical databases, evaluates functional predictions, and determines inheritance patterns without human intervention. The weighted scoring framework automatically synthesizes all these assessments into a final pathogenic classification. This self-service capability achieves full automation while maintaining precision through comprehensive multi-criteria evaluation.
Solution Approach 2:
The system incorporates feedback mechanisms where classification results can be validated against known pathogenic variants in clinical databases, and scoring weights can be adjusted based on performance metrics. The automated system learns from and adapts to validation feedback, improving classification accuracy over time while maintaining high automation levels. This feedback loop ensures precision without requiring continuous manual interpretation.
Data Source
AI summary
An automated pathogenic mutation classification method is provided, which includes producing a population score using a population database based on related information. A variant type score is produced using a variation pattern prediction tool based on the related information. A clinical score is produced using the related information or a clinical database based on the related information. A functional score is produced using a functional variant hazard prediction tool based on the related information. The population score, the variant type score, the clinical score, and the functional score are summed to obtain a pathogenic score. Probability that mutation sites suffer from a corresponding disease is determined based on the pathogenic score. When the pathogenic score is higher, the probability of the mutation sites suffering from the corresponding disease is higher.
