Who was studied 39,106 European ancestry clinically diagnosed cases, 46,828 European ancestry proxy cases, 401,577 European ancestry controls; replicated in 25,392 cases, 276,086 controls.
The effect
Each copy of the T allele carried 1.05 times the odds of Alzheimer's disease (95% confidence interval 1.03-1.07); p = 5 × 10−9.
How common The T allele had a frequency of about 24% in the people studied.
Where it sits Chromosome 19, band 19q13.33 — a synonymous change in SIGLEC11.
What each result means
C/CNo copy of the version the research linked to Alzheimer's disease. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Alzheimer's disease. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Alzheimer's disease. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs9304690
What is rs9304690?
rs9304690 is a single position in the genome, in or near the SIGLEC11 gene. Published research associates it with alzheimer's disease. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs9304690 linked to?
On MyGeneLog this position is linked to Alzheimer's Disease Risk (APOE). The research behind each link, and its sources, are set out on that condition page.
Does having rs9304690 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 rs9304690 come from?
GWAS Catalog, Nature genetics 2022, PMID:35379992. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
