23andMe Pharmacogenetics: How to Get a Drug Response Report From Your Existing Data

23andMe gives you raw genetic data: the genotype calls from the chip it ran on your saliva. What it does not give you is a guideline-based report on how those genes affect your medications. That is what Gene2Rx adds. Upload your 23andMe raw data file and Gene2Rx turns it into a pharmacogenetics report covering 110 medications, built on the same CPIC and FDA guidelines clinicians use. It runs in minutes, costs $5 for a starter report or $49 for the full report, needs no doctor's order, and never expires, because your DNA does not change. You already paid to have your DNA read; this unlocks the part of it that affects prescriptions.

23andMe's genotyping chip reads hundreds of thousands of positions, including many of the pharmacogenetic variants used in clinical testing: the markers for CYP2D6, CYP2C19, CYP2C9, SLCO1B1, VKORC1, DPYD, and more are sitting in your raw data file. 23andMe simply does not interpret most of them for drug response. The genotypes are there; what is missing is the analysis that turns them into per-medication guidance.

Gene2Rx reads your raw data, calls your metabolizer phenotype for each pharmacogene (poor, intermediate, normal, rapid, or ultrarapid), and maps each phenotype to specific recommendations for 110 medications, with every recommendation traceable to its CPIC or FDA guideline. The report spans psychiatry (antidepressants, antipsychotics, ADHD medications), cardiology (clopidogrel, warfarin, statins, metoprolol), pain (codeine, tramadol), chemotherapy (capecitabine, fluorouracil), transplant, and gastrointestinal drugs. It is delivered in minutes, no new sample and no prescriber required.

It is worth being clear about the limits. A 23andMe chip is a consumer product built for ancestry and traits, not a clinical-grade assay, and the raw data download is labeled as not for medical use. It also reads only the specific positions printed on the chip, so it does not detect structural variants such as gene duplications and deletions. That matters most for CYP2D6,^[1] where an extra gene copy can make someone an ultrarapid metabolizer and a deleted copy can leave almost no enzyme. For most prescribing questions your 23andMe data is a strong, low-cost starting point; for a high-stakes, one-time decision such as chemotherapy dosing, a clinician may still confirm a key result with a clinical-grade test.

23andMe does include an FDA-authorized pharmacogenetics report, but it is narrow by design: it reads a small, fixed set of variants in a few genes, is framed as wellness information, and explicitly tells you to confirm anything actionable with a clinical test. It does not give you guideline-based recommendations across your medication list. Gene2Rx reads far more pharmacogenetic variants from the same raw file and reports against 110 medications using CPIC and FDA dosing guidance.

Clinical pharmacogenetic tests like GeneSight run from a few hundred to a few thousand dollars, need a new DNA sample, and require a provider order. Because you already have 23andMe data, none of that applies: a Gene2Rx report is $5 for the starter tier, $35 for a psychiatric report, or $49 for the full 110-medication report, with no lab work to repeat. Your pharmacogenetic profile does not change over time, so a single report is a reference you will use for decades of prescribing decisions.

These are the main genes Gene2Rx reads out of your 23andMe data and what each one affects. The biology is the same no matter which data source you start from; what 23andMe provides is the raw genotype at these positions.

Your 23andMe raw data contains the genotypes for all of these genes; the only thing standing between that and actionable guidance is interpretation. Gene2Rx translates your genotypes into metabolizer phenotypes for each gene, then maps those phenotypes to specific medication recommendations anchored to CPIC^[1] and FDA^[9] guidelines, so the output reads the same way a clinical pharmacogenetic report would.

If you already have 23andMe data, there is little reason to wait: the data exists and the starter report is $5. It is most valuable if you are starting or already taking a medication with pharmacogenetic guidelines, if you have had side effects or poor response in the past, or if you simply want the information on file for future prescribing. Because your genotype never changes, one report serves you for life.

Only narrowly. 23andMe's FDA-authorized pharmacogenetics report reads a small fixed set of variants, is framed as wellness information, and recommends clinical confirmation before acting. Gene2Rx reads far more pharmacogenetic variants from the same raw data file and reports against 110 medications with CPIC and FDA guideline-based recommendations.

For the common variants, yes. 23andMe's genotyping chip reliably captures the pharmacogenetic markers that drive the majority of actionable recommendations. Two caveats are worth knowing: it is a consumer-grade product whose raw data is labeled not for medical use rather than a clinical-grade assay, and like all genotyping chips it does not detect structural variants such as CYP2D6 gene duplications or deletions. For the most complete picture, whole genome sequencing resolves more (and Gene2Rx accepts that too), and a clinician may confirm a high-stakes result with a clinical-grade test.

Yes. Your DNA does not change, so any chip version works. Older versions cover slightly fewer variants, but the core pharmacogenetic markers have been included since early 23andMe chips.

Those work too. Gene2Rx accepts 23andMe, AncestryDNA, and MyHeritage raw data, plus VCF files from whole genome sequencing. The process is the same: download your raw data and upload it. WGS and VCF uploads carry a $15 surcharge because they take more processing.
