Civic Search Variants

Search for variants in CIViC database. Returns a list of variants with their IDs and names. Use 'query' to search by variant name (e.g., 'V600E'), or 'gene'/'gene_name' to get all variants for a specific gene (e.g., 'EGFR'). To find a specific variant in a gene, combine gene_name + variant_name (e.g., gene_name='EGFR', variant_name='L858R'). Note: CIViC stores variants without gene prefix — do not combine gene and variant in a single string.
