A Nucleus Preview Alternative Built on Your Existing DNA
Looking for a cheaper or more couple-focused alternative to Nucleus Preview? The Genomisaur Preconception Report is $99 total for both parents, analyzes 100 simulated offspring, and accepts data you already have — including a Nucleus VCF if you already bought one.
At a glance
Couples who already have 23andMe, AncestryDNA, MyHeritage, or any WGS VCF and want a preconception report for both partners for $99 total.
Buyers who want Nucleus's own WGS sequencing included in the package and are happy with single-person analysis.

Feature comparison
Side-by-side on the things that actually change what the product does for you.
| Feature | Genomisaur | Nucleus Genomics | Edge |
|---|---|---|---|
| Base test you need | None — uses existing 23andMe, AncestryDNA, MyHeritage, or WGS VCF | Nucleus WGS (included) or bring your own VCF | |
| Whole genome sequencing | Supported via VCF upload (+$20) | Included in the test | |
| Preconception focus (two-parent analysis) | Yes — 100 simulated offspring genomes from both parents | Single-person report; couples buy two | |
| Polygenic risk scores included | 71 PRS across 14 categories | Broad PRS coverage; exact count varies | |
| Carrier screening | Cystic fibrosis, sickle cell, Tay-Sachs, SMA, and more | Extensive carrier screening panel | |
| Turnaround time | ~20 min (individual), ~2 hours (family) | Weeks (includes lab sequencing) | |
| Price (one-time) | $99 Family Full | $399 Nucleus Preview | |
| Data ownership & portability | You bring your own file; delete any time | Your data sits in Nucleus; portability depends on their policies |
What each one does well
Genomisaur
- ~10× cheaper per couple ($99 vs ~$798 for two Nucleus Preview tests)
- Two-parent analysis with 100 simulated offspring — something Nucleus does not offer
- Accepts Nucleus VCFs if you already have their data
- ~2 hour turnaround, no waiting on a lab
Nucleus Genomics
- WGS included in the price
- Deeper single-person rare-variant analysis
- Established brand
If you already have genetic data from any provider — including Nucleus itself — the Genomisaur Family Full Report at $99 is the best direct alternative to Nucleus Preview for couples. If you have no DNA data yet and want WGS bundled, buying Nucleus Preview and then uploading the resulting VCF to Genomisaur combines the two.
Frequently asked questions
Is Genomisaur a cheaper alternative to Nucleus Preview?
Yes — the Genomisaur Family Full Report is $99 one-time versus Nucleus Preview's listed $399. The difference is that Nucleus includes whole genome sequencing and Genomisaur assumes you already have genetic data (or can upload a VCF from any provider, including Nucleus, for +$20).
Can I upload my Nucleus Genomics data to Genomisaur?
Yes. Nucleus exports a VCF of your whole genome sequence. Upload it to Genomisaur and we compute all of our polygenic risk scores, trait predictions, and preconception analyses on top of it.
Do I need whole genome sequencing for a preconception report?
No. Consumer SNP arrays from 23andMe, AncestryDNA, or MyHeritage cover enough well-studied variants to produce meaningful polygenic risk scores and carrier screening results. WGS is a nice-to-have for rare-variant resolution, not a requirement.
Which one should I buy?
If you do not have any genetic data yet and want a WGS-backed report, Nucleus Preview is the most comparable product at ~$399. If you (or either parent) already have 23andMe, AncestryDNA, MyHeritage, or a VCF from any sequencing provider, Genomisaur's Family Full Report gives you preconception-specific outputs — 100 simulated offspring, carrier screening, PRS — at $99.
How does two-parent simulation work?
We model meiosis computationally: each simulated offspring inherits one chromosome copy from each parent, with crossover events shuffled in. Running 100 of those simulations gives you a distribution — "72 of 100 children had brown eyes, 20 hazel, 8 blue" — instead of a single deterministic guess.
Is this medical advice?
No. Both Nucleus Preview and Genomisaur are informational reports, not diagnostic tools. Carrier and risk results should be reviewed with a qualified healthcare provider or genetic counselor before making medical decisions.
Informational, not diagnostic
Consumer preconception reports — ours, Nucleus Genomics's, and others — are informational. Carrier and polygenic risk results should be discussed with a qualified healthcare provider or genetic counselor before making medical or reproductive decisions.
