from VCF files, identifying mutation types, affected genes, amino acid changes, and functional impact predictions.\n\n## Input\n- VCF format file (standard VCF 4.2 format)\n- Mutation list (format like \"BRCA1:c.68_69delAG\" or \"TP53:p.G245S\")\n\n## Steps\n\n### Step 1: Parse VCF or Mutation Format\n- Identify input format (VCF file or HGVS format)\n- VCF format parsing: Extract CHROM, POS, REF, ALT\n- HGVS format parsing: Use regex to extract gene name, variant position, variant type\n\n### Step 2: Determine Mutation Type\n- SNP (Single Nucleotide Polymorphism): REF and ALT have same length and both are 1 base\n- InDel (Insertion/Deletion): REF and ALT have different lengths, or contain \"ins\"/\"del\"\n- Large structural variants: Variants beyond single base range\n\n### Step 3: Identify Affected Genes and Transcripts\n- Query gene annotation database based on chromosome position\n- Use simplified gene position mapping table (built-in data)\n- Determine transcript ID and coding region position\n\n### Step 4: Predict Amino Acid Changes\n- DNA to RNA to amino acid translation\n- Identify amino acid substitution, frameshift, nonsense mutation caused by variant\n- Calculate protein length change after mutation\n\n### Step 5: Predict Functional Impact\n- Based on mutation position (domain, critical residue)\n- Based on amino acid property changes (polarity, charge, size)\n- Prediction classification: Benign / Likely Benign / VUS / Likely Pathogenic / Pathogenic\n- Provide confidence score (0-1)\n\n### Step 6: Output Annotation Results\n- JSON format output\n- Contains complete annotation information\n- Also output summary table\n\n## Output\nMutation annotation table (JSON format), containing the following fields:\n- mutation_id: Unique mutation identifier\n- gene: Affected gene\n- transcript: Transcript ID\n- chromosome: Chromosome\n- position: Genomic position\n- ref_allele: Reference allele\n- alt_allele: Alternative allele\n- variant_type: Variant type (SNP/InDel/Large Deletion etc.)\n- protein_change: Protein change description\n- aa_position: Amino acid position\n- original_aa: Original amino acid\n- substitute_aa: Substituted amino acid\n- functional_impact: Functional impact prediction\n- pathogenicity_score: Pathogenicity score (0-1)\n- interpretation: Interpretation\n- tools_used: List of annotation tools used\n\n## Tools\n- Python 3.8+\n- Standard library: re, json, sys\n- Built-in gene annotation database (simplified version)\n\n## Examples\n\n### Input Example\n```\nBRCA1:c.68_69delAG\nTP53:p.G245S\n17:g.41244938C>G\n```\n\n### Output Example\n```json\n{\n  \"mutations\": [\n    {\n      \"mutation_id\": \"BRCA1_c.68_69delAG\",\n      \"gene\":
