Family history is a lab result.
No vial. No sequencer. And it is the only clinical-grade signal your doctor still gets as anecdotes — so write it down once, graded and cited, and bring that to the appointment.
What the document looks like when the anecdotes are in.
| Pattern | Basis | Onset ages | Evidence grade | Suggested discussion |
|---|---|---|---|---|
| Breast cancer, maternal line | Grandmother, aunt, mother: one bloodline, three diagnoses | 47 · 51 · 44 | NCCN CAT. 1 | Genetics referral: meets criteria for counseling |
| Colorectal cancer, paternal side | Grandfather, dx 62. Single relative, later onset | 62 | USPSTF B | Screening from age 45; earlier start unlikely to be indicated |
| Type 2 diabetes, both lines | Father and maternal uncle, both lines | 55 · 58 | PATTERN-MATCHED | Lower confidence; review with your clinician |
Grades follow the published bodies: USPSTF A/B, NCCN Category 1, ACMG referral-indication criteria. How we build our insights.
The risk associated with one close affected relative, for some conditions. It rises with each additional relative.
Klemenc-Ketiš & Peterlin, PLOS One 2013Carried a clinically actionable genetic variant once a notable family history of cancer was taken into account, versus 1 in 47 at average risk.
Bylstra et al., Genome Medicine 2021Lower relative risk of coronary events with a healthy lifestyle, among those at high genetic risk.
Khera et al., N Engl J Med 2016Guideline start age for colorectal screening. Guidelines may start earlier still when family history points to higher risk.
USPSTF, JAMA 2021These are population figures, not a personal score. Your report never turns a family history into your own risk percentage; that assessment belongs to a clinician.
Chain of custody: it never leaves your hands.
A lab documents who touched a sample and when. For readable data, that record has one name on it: yours. An employee with full admin access reads ciphertext.
- Your passphrase never leaves the device
It is stretched into an encryption key locally (Argon2id), and the passphrase itself is never transmitted.
- Each record is sealed before it travels
Every entry is individually encrypted with XChaCha20-Poly1305, unique nonce per record, before it reaches the network.
- Relatives receive keys in sealed boxes
Invitations deliver the key via X25519, and removing a member rotates the family key.
- The AI call goes around us
Insight generation runs from your device direct to the model provider. Our servers mint a short-lived token and are never on the call path.
