# Look up a MANE gene by symbol (jump-to-gene for the browser search)

`GET /sessions/{session_id}/browser/gene/{symbol}`

## Request

- Base URL: `https://api.helena.bio` (the document declares no server; this is the origin it was published from)
- URL: `https://api.helena.bio/sessions/{session_id}/browser/gene/{symbol}`
- Auth: HTTP bearer

Return the MANE coordinates for one gene symbol, anywhere in the genome.

Org-scoped + READ-ONLY by construction (only a SELECT against the read-only
reference_db singleton). Powers the search box's jump-to-gene: the frontend
calls this when a typed symbol is not among the genes in the loaded region.
404 if the symbol is unknown to MANE.

## Path parameters

- `session_id` string, uuid, required
- `symbol` string, required

## Response `200`

Successful Response

- BrowserGeneOut: A gene model from MANE (frontend BrowserGene). MANE carries the CDS envelope (cds_start, cds_end), not a per-exon model, so exons is returned as an empty array (a recorded Section 6 limitation; the frontend Panel tolerates an empty exons array).
  - `chrom` string, required
  - `symbol` string, required
  - `start` integer, required
  - `end` integer, required
  - `strand` string, nullable
  - `exons` integer[]

## Other responses

- `422`: Validation Error
