Nucleus Genomics and Atlagene are both modern entrants in consumer genomics, but they're optimizing for different audiences. Here's a direct comparison.
TL;DR
| Nucleus Genomics | Atlagene | |
|---|---|---|
| Test type | 30x whole genome sequencing | Reads existing DNA files |
| Need to take a new test? | Yes ($399 kit) | No |
| Annual fee | $39/yr after kit | $0–349/yr depending on tier |
| Coverage | Whole genome (~3B base pairs) | ~600K-700K SNPs from consumer arrays, full WGS files supported |
| Strongest use case | Fertility / IVF planning | Existing-file health analysis |
| Pharmacogenomics | Available | 200+ drugs |
| AI chat | Limited | Helix AI (Premium) |
| Family planning | Strong (post-2025 pivot) | Family plan with parent-child matching |
| Physician review | No | Yes (bundled or pay-per) |
What Nucleus is good at
Nucleus offers 30x whole genome sequencing at $399 — a deeper test than the SNP arrays 23andMe and AncestryDNA use. WGS picks up rare variants that consumer chips miss entirely, and Nucleus has invested heavily in disease and trait reporting.
In 2025, Nucleus pivoted hard into the fertility / pre-conception / embryo-selection space. Their public messaging is now centered on "have your best baby," and they've integrated with IVF clinics. If you're planning a family and want WGS for both partners + embryo selection, Nucleus is the most direct option.
The $39/year subscription is mainly for ongoing report access and new feature releases. Nucleus does not offer pharmacogenomics, AI chat, or physician review as of late 2025.
What Atlagene is good at
Atlagene's wedge is different: we read DNA files you already have. If you've taken any DNA test (23andMe, AncestryDNA, MyHeritage, Nebula, Dante Labs, or any clinical VCF), upload the file and get 21-category analysis without paying for a new test.
For users who already have a file, the comparison is:
- Nucleus: $399 + $39/yr to do a new (deeper) test
- Atlagene: free to upload your existing file; Premium $14.99/mo to unlock all features
If you don't already have a DNA file and want WGS-depth, Nucleus is the more direct path. If you have an existing 23andMe / AncestryDNA file, Atlagene gets you 20 health categories from what you already paid for.
For ongoing engagement, Atlagene includes Helix AI chat (ask questions about your results in plain language), pharmacogenomics for 200+ drugs, polygenic risk scores, and personalized supplement plans across all 20 health categories. Nucleus's offering is currently more focused on disease reports.
Family / pre-conception comparison
Nucleus is now leading on fertility. Their embryo-selection integration with IVF clinics is unique.
Atlagene's Family plan approach is different: parent-child genetic matching from existing DNA files, carrier compatibility analysis across both parents, and per-member dashboards for ongoing health monitoring. It's stronger for "ongoing family health" than for "embryo selection in an IVF cycle."
If you're in active IVF planning, Nucleus has the integrations. If you want longitudinal family health, Atlagene's Family plan covers that better.
WGS file users
If you already own a WGS file (Nebula, Dante Labs, clinical exome), Atlagene supports the full file — WGS uploads get a deeper analysis with 7x more variants than consumer arrays. This is included in Premium.
You don't need to re-do WGS through Nucleus to get health analysis from your existing WGS file.
Pricing comparison (illustrative, 2-year horizon)
- Nucleus (kit + 2yr): $399 + 2×$39 = $477
- Atlagene Premium (no kit needed if you have a file): 2×$119 = $238
- Atlagene Premium + Physician (2yr): 2×$249 = $498
- 23andMe one-off + Atlagene Premium 2yr: ~$99 (kit) + $238 = $337
For someone without a DNA file: 23andMe + Atlagene is cheaper than Nucleus and gives you ancestry, relative-finding, and 20 health categories. For someone wanting WGS-depth, Nucleus is the direct path.
Bottom line
- Already have a DNA file? Atlagene is the cheaper, faster path to 21-category health analysis.
- In active IVF/fertility planning? Nucleus is now optimized for that.
- Want WGS depth and don't have one? Nucleus.
- Want longitudinal family health, AI chat, pharmacogenomics? Atlagene.
