# Get AD recurrence risk findings

`GET /sessions/{session_id}/recurrence-risk`

## 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}/recurrence-risk`
- Auth: none declared

Return autosomal dominant recurrence risk findings for a session.

    Identifies P/LP heterozygous variants in AD-only genes with 50%
    transmission probability to offspring.

    This is NOT carrier status. AD heterozygotes are potentially affected
    individuals, not healthy carriers (ACMG terminology).

    Results are pre-computed by Stage 6 (Reproductive Risk Annotation).
    Use force=true to re-run detection.

## Path parameters

- `session_id` string, uuid, required

## Query parameters

- `force` boolean: Force re-run of AD risk detection

## Response `200`
