Where this position leads

What the study found

Who was studied 200,762 European ancestry individuals (MTAG effective sample size boosted by alcohol use disorder and nicotine dependence samples).

The effect Each copy of the T allele shifted the measure 0.017 lower (95% confidence interval 0.011-0.023); p = 4 × 10⁻⁸.

How common The T allele had a frequency of about 45% in the people studied.

Where it sits Chromosome 1, band 1p21.3 — in an intron of DPYD.

What each result means

C/C No copy of the version the research linked to Cannabis use disorder (MTAG). This is the starting point the study compared everyone against.

C/T One copy of the version the research linked to Cannabis use disorder (MTAG). That is a smaller link than two copies.

T/T Two copies of the version the research linked to Cannabis use disorder (MTAG). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs3897854

What is rs3897854?

rs3897854 is a single position in the genome, in or near the DPYD gene. Published research associates it with cannabis use disorder (mtag). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs3897854 linked to?

On MyGeneLog this position is linked to Cannabis Use Disorder. The research behind each link, and its sources, are set out on that condition page.

Does rs3897854 affect how medicines work?

DPYD carries pharmacogenomic findings for Fluoropyrimidines. That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.

Does having rs3897854 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs3897854 come from?

GWAS Catalog, Nature genetics 2023, PMID:37985822. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
