• server.py:250-274 (handler)

  The handler function `get_str_info` implements the tool logic for retrieving short tandem repeat information. It validates the dataset version and uses `run_query_with_metadata` to execute the query.

  def get_str_info(
      reference_genome: str,
      id: str,
      dataset: str = 'gnomad_r4'
  ) -> dict:
      """
      [gnomAD API] Retrieve STR info (v4 only)
      Args:
          reference_genome (str): Reference genome (GRCh38)
          id (str): STR ID (e.g. ATXN1)
      Returns:
          dict: STR info
      Note:
          Not supported in v2/v3.
      """
  
      if dataset != 'gnomad_r4':
          raise ValueError("Only v4 is supported for STR info.")
  
      variables = {
          'dataset': dataset,
          'reference_genome': reference_genome,
          'id': id,
      }
      return run_query_with_metadata('short_tandem_repeat', variables)
