POINEER Platform
POI Network for Early Evaluation and Recognition
Platform Overview
POINEER is a comprehensive analysis platform designed to predict Primary Ovarian Insufficiency (POI) risk based on mutational profiles. The platform provides a complete workflow from MAF file analysis to risk prediction through four integrated analysis steps.
注意:如需要使用模型进行预测,mutations应是MAF < 1% in EAS population in public databases (including ExAC, gnomAD, and 1000 Genomes)。
Analysis Workflow
The POINEER platform follows a four-step analysis pipeline:
Mutation Spectrum
Sample Distribution] B -->|Step 2| C[Gene-Sample
Mutation Matrix] C -->|Step 3| D[Gene Set Mutation
Burden Matrix] D -->|Step 4| E[POI Risk Prediction
High/Low Risk] E -->|Step 5| F[Molecular Subtype
Distribution] style A fill:#e1f5ff style B fill:#fff4e1 style C fill:#e8f5e9 style D fill:#f3e5f5 style E fill:#ffebee style F fill:#e3f2fd
MAF File Analysis
Upload and analyze MAF format mutation files. Generate basic statistics, mutation spectrum plots, and sample distribution visualizations.
Gene-level Analysis
Convert site-level mutations to gene-level sample-gene mutation matrix. Count amino acid-changing mutations per gene per sample.
Gene Set Analysis
Calculate gene set mutation burden by counting mutated genes within each gene set per sample. Normalize by gene set size and perform statistical analysis.
Risk Prediction
Aggregate gene set mutations by cluster, calculate cluster-level mutation burden, and use pre-trained POINEER model to predict POI risk.
Step 5: Molecular Subtype
Molecular subtyping for POI-predicted (high-risk) samples based on mutations in key genes, and distribution statistics.
