Genomic Variant Analysis & Interpretation
Analyze and prioritize genomic variants with clinical insights for research
What You Can Do
Upload and analyze VCF files to identify, assess, and prioritize genomic variants based on quality metrics and clinical relevance. Claude systematically interprets variant calls, evaluates their significance for disease and drug targets, and generates structured reports for downstream analysis in research and discovery workflows.
Features
Automatically parse and validate VCF format genomic data, extracting variant positions, alleles, quality scores, and genotype information
Evaluate variants using standard quality thresholds including read depth, mapping quality, allele frequency, and filter status
Prioritize variants by estimated impact on phenotypes, disease associations, and drug target potential using evidence-based scoring
Cross-reference variants with functional annotations, conservation scores, and known disease associations from public databases
Analyze variants across multiple samples to identify shared pathways, inheritance patterns, or cohort-level trends
Create comprehensive variant reports with tables, summaries, and clinical interpretations ready for publication or clinical action
Output prioritized variant lists in multiple formats (TSV, JSON, spreadsheet) compatible with downstream bioinformatics pipelines
Example Output
Example 1: Variant Prioritization Summary
| Chromosome | Position | Ref/Alt | Quality | Depth | AF | Impact | Clinical Score |
|---|---|---|---|---|---|---|---|
| chr17 | 41,196,312 | G/A | 99 | 145x | 0.48 | Missense | 8.7 |
| chr13 | 32,889,611 | C/- | 87 | 98x | 0.51 | FrameShift | 9.2 |
| chr19 | 44,908,684 | T/G | 45 | 32x | 0.25 | Synonymous | 2.1 |
Example 2: Clinical Interpretation
Variant NM_000546:c.818G>A (p.Arg273His) in TP53:
- Quality: PASS (GQ=99, DP=145x)
- Significance: Hotspot mutation associated with Li-Fraumeni syndrome and cancer predisposition
- Drug Relevance: Potential target for p53-reactivating compounds
- Recommendation: HIGH PRIORITY for validation and follow-up studies
Example 3: Cohort-Level Summary
Across 50 samples, 342 variants pass QC filters. Top disease associations: Cardiovascular (12%), Metabolic (18%), Cancer (24%). Variants in BRCA1/BRCA2 detected in 3 samples with inheritance pattern consistent with autosomal dominant transmission.
