Who was studied 148,726 European ancestry cases, 965,732 European ancestry controls.
The effect
Each copy of the T allele shifted the measure 0.042 higher (95% confidence interval 0.028-0.056); p = 1 × 10−9.
How common The T allele had a frequency of about 13% in the people studied.
Where it sits Chromosome 1, band 1q32.1 — in an intron of PM20D1-AS1.
What each result means
A/ANo copy of the version the research linked to Type 2 diabetes. This is the starting point the study compared everyone against.
A/TOne copy of the version the research linked to Type 2 diabetes. That is a smaller link than two copies.
T/TTwo 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 rs7538321
What is rs7538321?
rs7538321 is a single position in the genome, in or near the PM20D1-AS1 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 rs7538321 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 rs7538321 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 rs7538321 come from?
GWAS Catalog, Nature genetics 2020, PMID:32541925. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
