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 C; the catalogue records no effect size
; p = 6 × 10−9.
How common The C allele had a frequency of about 2% in the people studied.
Where it sits Chromosome 6, band 6q27 — in an intron of PDE10A.
What each result means
C/CTwo 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.
C/TOne copy of the version the research linked to Type 2 diabetes. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Type 2 diabetes. This is the starting point the study compared everyone against.
rs77273391 is a single position in the genome, in or near the PDE10A 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 rs77273391 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 having rs77273391 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 rs77273391 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.
