Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−8, with 1 associations in the GWAS Catalog.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What the study found

Who was studied 50,251 African American cases, 103,909 African American controls, 88,109 East Asian ancestry cases, 339,395 East Asian ancestry controls, 242,283 European ancestry cases, 1,569,734 European ancestry controls, 29,375 Hispanic cases, 59,368 Hispanic controls, 1,602 South African ancestry cases, 976 South African ancestry controls, 16,832 South Asian ancestry cases, 33,767 South Asian ancestry controls.

The effect The reported allele is G; the catalogue records no effect size ; p = 2 × 10−8.

How common The G allele had a frequency of about 14% in the people studied.

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

What each result means

A/A No copy of the version the research linked to Type 2 diabetes. This is the starting point the study compared everyone against.
A/G One copy of the version the research linked to Type 2 diabetes. That is a smaller link than two copies.
G/G Two copies of the version the research linked to Type 2 diabetes. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs3778156

What is rs3778156?

rs3778156 is a single position in the genome, in or near the OPRM1 gene. Published research associates it with type 2 diabetes. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs3778156 linked to?

On MyGeneLog this position is linked to Type 2 Diabetes. The research behind each link, and its sources, are set out on that condition page.

Does rs3778156 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 rs3778156 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 rs3778156 come from?

GWAS Catalog, Nature 2024, PMID:38374256. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
