Turn Your AncestryDNA Data into Medication Safety Insights

Your AncestryDNA Data Contains More Than Ancestry

AncestryDNA tells you about ethnicity and family connections — but your raw data also contains clinically relevant variants in genes like CYP2D6, CYP2C19, CYP2C9, and VKORC1. These genes affect how your body metabolizes medications — from blood thinners to antidepressants to pain medications.

AncestryDNA does not analyze these genes. DecodeMyBio does.

What Your AncestryDNA Data Covers

AncestryDNA genotyping chips include many of the same SNPs found in pharmacogenomic panels. However, coverage varies by chip version, and AncestryDNA typically covers fewer pharmacogenomic markers than 23andMe.

• AncestryDNA v2+ data typically includes 7–15 pharmacogenomic markers across key drug-metabolizing genes.
• 23andMe data typically includes 15–25 markers for the same genes.
• DecodeMyBio requires a minimum of 7 markers to generate a report. If your file falls below this threshold, the system will let you know before you pay.

Your report will indicate a confidence level: high (15+ markers) or moderate (7–14 markers). Both levels produce clinically referenced findings, but more markers means a more complete picture.

Genes Typically Available in AncestryDNA Data

• CYP2C19 — affects clopidogrel, omeprazole, escitalopram
• CYP2C9 — affects warfarin dosing
• CYP2D6 — affects codeine, antidepressants, tramadol
• VKORC1 — affects warfarin sensitivity

How It Works

1. Export your raw data from AncestryDNA — go to Settings → DNA Settings → Download Raw DNA Data.
2. Upload to DecodeMyBio — takes about 2 minutes. We accept AncestryDNA text and CSV formats, including compressed files.
3. Get 9 free trait insights immediately — caffeine metabolism, lactose tolerance, and more while your data is analyzed.
4. Unlock your full Medication Safety Report — 150+ drug-gene interactions analyzed, with a clinician pocket summary you can share with your doctor.

For details on how your data is analyzed, see our methodology page.

What the Report Includes

• 150+ drug-gene interactions analyzed across up to 14 pharmacogenes.
• Risk snapshot: summary of significant and moderate findings.
• Medication checklist: 48 named medications with CPIC guideline actions.
• Clinician pocket summary: one-page overview formatted for your healthcare provider.
• Confidence indicator: your report clearly states how many markers were available and the resulting confidence level.

Built on CPIC Clinical Guidelines

DecodeMyBio maps your genetic variants to published pharmacogenomic guidelines from CPIC (Clinical Pharmacogenetics Implementation Consortium) — the same evidence base used in hospital pharmacogenomics programs.

This is not a proprietary algorithm. Every finding references specific guideline recommendations that you and your healthcare provider can verify independently. See our methodology for details.

Limitations

• AncestryDNA genotyping arrays cover fewer pharmacogenomic markers than 23andMe. Reports generated from AncestryDNA data may have moderate confidence depending on chip version.
• Consumer genotyping arrays cannot detect gene deletions or duplications, which affect some CYP2D6 phenotype classifications.
• Pharmacogenomic results do not predict whether a medication will work for you. They indicate how your genetics may affect drug metabolism.
• This is not medical advice. All medication decisions should be made with your healthcare provider. See our full limitations page.
