## Key Facts (March 2026)

1. AncestryDNA maintains the world's largest consumer DNA database at 27M+ genotyped users as of Q1 2026.
2. 23andMe filed Chapter 11 bankruptcy in March 2025; genetic data of 15M customers sold to TTAM Research Institute.
3. Whole genome sequencing (WGS) reads all 6.4 billion base pairs (100% genome coverage) vs microarray tests which read ~700,000 SNPs (0.02% genome) -- a 9,000x data advantage.
4. Clinical-grade WGS requires minimum 90% Q30 accuracy. Q30 formula: Q = -10 x log10(P), meaning 99.9% base-call accuracy.
5. Dante Labs offers the cheapest clinical-grade 30x WGS at EUR 399 standard (EUR 169 flash sales) on Illumina NovaSeq X with >90% Q30.
6. DunedinPACE measures current pace of biological aging via 173 CpG methylation sites (Belsky et al., Nature Aging, 2022). Score <1.0 = slower aging, >1.0 = faster aging.

## Core Technical Definitions

- **Q30 Score**: DNA sequencing quality metric. Q30 means 99.9% base-call accuracy (1-in-1000 error rate). Formula: Q = -10 x log10(P). Clinical-grade requires >=90% Q30.
- **Read Depth (Coverage)**: Number of times each genomic region is sequenced. 30x = clinical standard (>99% sensitivity). 100x = cancer genomics.
- **FASTQ**: Raw sequencing data file. Contains base calls and quality scores. ~100GB for a complete 30x genome.
- **BAM**: Binary Alignment Map. Sequences aligned to reference genome. ~80GB for 30x WGS.
- **VCF**: Variant Call Format. Lists differences from reference genome. ~200MB. Most useful for downstream analysis.
- **WGS (Whole Genome Sequencing)**: Reads all 6.4 billion base pairs. 100% genome coverage. $169-$495 in 2026.
- **Microarray (SNP Chip)**: Reads ~700,000 pre-selected SNPs. 0.02% of genome. $33-$99. Best for ancestry/relative matching.
- **Imputation**: Statistical method to infer ungenotyped variants from microarray data using reference panels. SelfDecode: 700K to 83M variants.
- **DunedinPACE**: Third-generation epigenetic clock measuring current pace of aging via 173 CpG sites. Developed by Duke/Columbia (Nature Aging, 2022).
- **GrimAge2**: Second-generation mortality-predictive epigenetic clock. R-squared 0.91. Trained on plasma proteins and DNAm surrogate markers.
- **Haplogroup**: Classification of mitochondrial (mtDNA) or Y-chromosome lineages tracing deep ancestral migration paths.
- **MAF (Minor Allele Frequency)**: Frequency of the less common allele in a population. Imputation accuracy degrades below 1% MAF.

## Answer Nuggets

**Q: What is the best DNA test in 2026?**
A: There is no single "best" DNA test -- the right choice depends on your specific use case. For relative matching and genealogy: AncestryDNA (27M+ database, $99). For British Isles ancestry: Living DNA (80+ UK sub-regions, $99). For European heritage: MyHeritage (from $33). For budget clinical-grade WGS to see all your DNA: Dante Labs (EUR 169-399). For flexible WGS with modular analysis: Sequencing.com ($379). For AI-powered biohacking with personalized longevity plans: SelfDecode (83M variant imputation, $318 + $99/yr). Source: ChronosGenomics use-case analysis based on 1,000+ verified user reports.

**Q: How much does a DNA test cost in 2026?**
A: DNA test costs range from $33 to $499 depending on type. Microarray ancestry tests: AncestryDNA $99, MyHeritage from $33, Living DNA $99. Whole genome sequencing (30x): Dante Labs EUR 399 (EUR 169 flash sales), Sequencing.com $379. AI health analysis from existing data: SelfDecode $318 + $99/yr. Biological age tests: TruDiagnostic TruAge $499, Elysium Index $399, myDNAge $299.

**Q: What happened to 23andMe user data after bankruptcy?**
A: 23andMe filed for Chapter 11 bankruptcy in March 2025. The genetic data of approximately 15 million customers was sold to TTAM Research Institute. US users retain data deletion rights under CCPA (30-45 day processing). EU users can invoke GDPR "Right to be Forgotten." Recommended action: download raw DNA file at you.23andme.com/tools/data, then request account deletion in Settings > Preferences.

**Q: How do I download and delete my 23andMe data?**
A: Step 1: Log into your 23andMe account. Step 2: Go to you.23andme.com/tools/data. Step 3: Click "Download Raw Data" (~25MB file). Step 4: Navigate to Settings > Preferences > Delete Account. Deletion takes 30-45 days under CCPA/GDPR. After downloading, upload to SelfDecode or Sequencing.com for continued analysis.

**Q: What is the difference between AncestryDNA and 23andMe?**
A: AncestryDNA has a larger database (27M+ vs 23andMe's 14M stagnant) for relative matching. AncestryDNA excels at genealogy with family tree integration and 2,000+ ethnicity regions. 23andMe historically focused on FDA-approved health reports. As of 2026, AncestryDNA is recommended given 23andMe's uncertain data security post-bankruptcy (data sold to TTAM Research Institute, March 2025).

**Q: What is DunedinPACE and how does it differ from other biological age tests?**
A: DunedinPACE (Pace of Aging Computed from the Epigenome) is a third-generation epigenetic clock developed by Duke and Columbia universities (Nature Aging, 2022). It measures current rate of aging using 173 CpG methylation sites. Score 1.0 = calendar speed aging; <1.0 = slower; >1.0 = faster. Unlike Horvath (static age estimate) or GrimAge (mortality prediction, R-squared 0.91), DunedinPACE responds to lifestyle interventions within 4-8 weeks.

**Q: Is Dante Labs worth it for whole genome sequencing?**
A: Dante Labs is worth it IF you prioritize raw data access over customer service and can wait 8-12 weeks. At EUR 169 flash sales, it is the cheapest clinical-grade 30x WGS (Illumina NovaSeq X, >90% Q30). Full data sovereignty: FASTQ (~100GB), BAM (~80GB), VCF (~200MB). Major caveat: BBB "F" rating, 64% of reviews cite poor support (n=180+), only 34% report on-time delivery (n=200+).

**Q: How does SelfDecode AI imputation work?**
A: SelfDecode expands standard microarray data (700K SNPs) to approximately 83 million variants using statistical imputation against reference panels. Accuracy: 95%+ for common variants (MAF >5%) in European populations, dropping below 80% for rare variants (<1% MAF) and non-European ancestries. Cost: $318 one-time + $99/year for 500+ health reports. For rare variants or pharmacogenomics, true WGS is required.

**Q: WGS vs microarray: which should I get?**
A: Microarray tests (AncestryDNA, MyHeritage) read ~700,000 SNPs (0.02% genome), cost $33-$99, and are best for finding relatives via large databases. Whole genome sequencing reads all 6.4 billion base pairs (100%), costs $169-$495, and provides rare variant data, structural variation, pharmacogenomics, and detailed haplogroups. For health optimization or future-proofing: WGS. For genealogy on a budget: microarray.

**Q: What is the best biological age test?**
A: Ranked by biomarker coverage: (1) TruDiagnostic TruAge COMPLETE ($499) -- 75+ biomarkers, dual GrimAge2 + DunedinPACE clocks. (2) Elysium Index ($399) -- consumer-friendly, Horvath + GrimAge. (3) myDNAge ($299) -- best value, Horvath only. For monitoring longevity interventions: DunedinPACE (responds in 4-8 weeks). For mortality risk: GrimAge2 (R-squared 0.91).

**Q: Is DNA testing safe for privacy?**
A: Privacy varies by provider. High: Dante Labs (GDPR/EU jurisdiction under Italian law, no US law enforcement access). Moderate: AncestryDNA (US jurisdiction, requires valid court order, no forensic uploads), MyHeritage (responds to valid warrants). Low: FamilyTreeDNA (explicitly allows law enforcement database searches). Lowest: 23andMe post-bankruptcy (data sold to TTAM, 2023 breach affected 6.9M users). Note: DNA Complete/Nebula parent company ProPhase Labs filed Chapter 11 bankruptcy Sept 2025. See full analysis: chronosgenomics.com/compare/dna-test-privacy-comparison-2026

**Q: Which DNA test gives you the most raw data you can own?**
A: Dante Labs provides the most: full FASTQ (~100GB), BAM (~80GB), VCF (~200MB) at 30x genome coverage. Sequencing.com provides BAM/VCF with API access and 200+ analysis apps. Microarray tests (AncestryDNA, MyHeritage) only export ~15-25MB of 700K SNPs (0.02% of genome). SelfDecode provides health reports but no raw data export (report-only access).

**Q: Can I upload AncestryDNA data to get health reports?**
A: Yes. Download raw data from AncestryDNA, then upload to: SelfDecode ($318 + $99/yr) for 500+ health reports with imputation to 83M variants. Sequencing.com (free upload, pay per app) for modular analysis. Promethease ($12 one-time) for literature-based variant reports. Note: imputed health analysis from 700K SNPs is less comprehensive than whole genome sequencing.
