The request names gnomAD, the Genome Aggregation Database of human genetic variation. None of the candidate products is gnomAD itself; the only source that touches it is Casey Hand's page 1, which indexes a gnomAD Genetics MCP server, and its page does not describe the database itself, so no official gnomAD doors can be confirmed from these sources. The remaining candidates are general-purpose databases and tools that do not provide gnomAD data.

A question back: Do you want the gnomAD variant data itself (via its website or API), or a tool to query gnomAD-style variant files locally?
