gnomad_list_gene_variants

List every gnomAD variant in a gene, transcript, or region with allele frequencies and predicted consequences, optionally filtered to one consequence class (lof, missense, synonymous, other) and/or a maximum allele frequency. The full result is staged on a DataCanvas table named gene_variants and an inline preview is returned alongside canvas_id and table_name — run gnomad_dataframe_query against them to rank by AF, count by consequence, or group across the complete set rather than the preview. When the canvas is disabled (CANVAS_PROVIDER_TYPE != duckdb) the tool returns a capped inline preview with spilled=false and canvas_id empty; the SQL path is then unavailable. Supply exactly one of gene, transcript_id, or region. Echoes the effective dataset and build.
