Free APOE raw data checker
Check APOE markers in your raw DNA file.
Drop in a 23andMe, AncestryDNA, or MyHeritage raw genotype file to see whether it contains APOE rs429358 and rs7412. The scan runs locally in your browser and shows raw marker strings only, not APOE e-status or disease-risk interpretation.

This checker reports marker presence and raw genotype strings only. It does not infer APOE e2/e3/e4 status, diagnose disease, estimate Alzheimer risk, recommend medical action, or send genotype data to GenoSight.
Decide whether you want this information before checking.
APOE can be psychologically and practically sensitive. MedlinePlus describes APOE e4 as a risk factor for late-onset Alzheimer disease, not a diagnosis, and US GINA protections do not cover life, disability, or long-term care insurance.
What this checker looks for
The goal is narrow on purpose: answer whether the two common APOE raw-data markers are present before anyone tries to interpret them.
APOE rs429358
One of the two raw-data markers commonly used in APOE e2/e3/e4 context when both markers are present and reliable.
APOE rs7412
The second marker commonly paired with rs429358. This checker shows the raw genotype string only.
Report context
GenoSight handles APOE as sensitive educational content with lipid, cognitive-aging, genetic-counseling, and insurance-boundary caveats.
Why the checker avoids interpretation
APOE is not like a casual caffeine or taste marker. A raw genotype string can be incomplete, and the personal meaning can be heavy. GenoSight keeps this free page to marker presence and handles broader context only inside explicit educational report flows.

- Runs locally in your browser

- Does not infer APOE e2/e3/e4 status on this page
- Does not estimate Alzheimer disease risk or recommend medical action
Source boundaries
GenoSight keeps APOE claims narrow and source-linked. The checker is a local preflight tool; it is not a medical device or a substitute for clinical genetic counseling.
APOE raw data checker questions
Can I check APOE from 23andMe raw data?
Often, yes, when a compatible raw genotype file includes usable rs429358 and rs7412 calls. Coverage can vary by provider and chip version.
Can I check APOE from AncestryDNA or MyHeritage raw data?
Yes, when the file is a compatible raw genotype download and includes the relevant APOE markers. Missing coverage should not be treated as a medical negative result.
Does this page tell me my APOE e2/e3/e4 status?
No. This page only shows marker presence and raw genotype strings. APOE status and disease-risk context are sensitive and should be handled with careful caveats.
Should I check APOE if I am not sure I want to know?
Pause first. APOE can affect how people think about future health, family risk, and insurance decisions. If dementia risk runs in your family or you feel unsure, consider a genetic counselor before checking.
