AncestryDNA COMT raw data
Does AncestryDNA test COMT?
AncestryDNA is not a clinical COMT test, but its raw data export can often be searched for common COMT markers. GenoSight can check a compatible AncestryDNA file and turn supported findings into a cautious educational report.
What to search
Start with exact rsIDs, then interpret carefully.
- COMT Val158Met: rs4680
- COMT context marker: rs4633
- MTHFR context: rs1801133 and rs1801131
- Coverage varies by file and chip version
The practical answer
People use "test COMT" to mean several different things. For AncestryDNA, the useful path is raw-data marker lookup followed by context-aware interpretation, not a single-SNP verdict.
AncestryDNA is not a clinical COMT test
AncestryDNA is built around ancestry, traits, and matching. A downloaded raw data file can be useful for educational re-analysis, but it is not clinical confirmation.
Use the raw data file, not an ethnicity report
Ancestry says DNA Data is downloadable as a text file. For COMT lookup, you need that raw genotype file, not screenshots, family trees, or ethnicity results.
Check marker coverage directly
The common COMT marker people search for is rs4680 Val158Met. Coverage can change by chip version, so check the file rather than assuming.
Source boundaries
Ancestry describes DNA Data as uninterpreted raw data that can be downloaded as a text file, and says the downloaded copy is no longer protected by Ancestry account security. Keep the file private and treat all re-analysis as educational context.
AncestryDNA and COMT questions
Does AncestryDNA include COMT in raw data?
Some AncestryDNA raw files may include COMT rsIDs such as rs4680, but coverage can vary by test version and provider updates. The safest answer is to search the raw file or use a local marker checker.
Where do I find AncestryDNA raw data?
Ancestry says the test owner can request DNA Data from DNA Settings, confirm the request, verify the account, and receive an email link. The downloaded file is typically named dna-data-date.zip.
Can GenoSight read AncestryDNA raw data for COMT?
Yes. GenoSight can analyze compatible AncestryDNA raw data files and frame COMT alongside MTHFR, caffeine and stimulant context, stress, sleep, goals, and report caveats. It is educational only.
Why do AncestryDNA letters sometimes differ from other sites?
Ancestry states that it reports SNP calls on the genomic forward strand with respect to GRCh37. Other tools may display variants differently, so GenoSight separates marker detection from interpretation.
