What the study found

Who was studied 88,114 European ancestry individuals.

The effect Each copy of the C allele carried 1.14 times the odds of Opioid addiction (multi-trait analysis) (95% confidence interval 1.095-1.196); p = 3 × 10−9.

Where it sits Chromosome 6, band 6q25.2 — in an intron of OPRM1.

What each result means

C/C Two copies of the version the research linked to Opioid addiction (multi-trait analysis). That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to Opioid addiction (multi-trait analysis). That is a smaller link than two copies.
T/T No copy of the version the research linked to Opioid addiction (multi-trait analysis). This is the starting point the study compared everyone against.

Questions about rs9478500

What is rs9478500?

rs9478500 is a single position in the genome, in or near the OPRM1 gene. Published research associates it with opioid addiction (multi-trait analysis). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does rs9478500 affect how medicines work?

OPRM1 carries pharmacogenomic findings for Opioids. 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 rs9478500 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 rs9478500 come from?

GWAS Catalog, Scientific reports 2022, PMID:36207451. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
