Turn Your AncestryDNA Data into Medication Safety Insights

Does AncestryDNA Offer Pharmacogenetics?

No — AncestryDNA does not offer pharmacogenetics or report on how your genes affect medications. But the raw data file you can download from AncestryDNA contains many of the same pharmacogenetic markers a clinical panel looks at. DecodeMyBio reads those markers from your existing file and maps them to CPIC drug-gene guidelines — so you get AncestryDNA pharmacogenetics insights without ordering a new test.

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 your results. If your file falls below this threshold, the app will tell you before you decode.

Decode+ 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. See your free genome overview — get an at-a-glance view of your data while it’s analyzed. Creating an account and uploading is always free.
4. Unlock your full medication results in Decode+ — 150+ drug-gene interactions analyzed across your pharmacogenes.

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

What’s Inside Decode+

• 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.
• Confidence indicator: Decode+ 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. Results 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.
