Who was studied 128,681 European ancestry cases, 849,833 European ancestry controls.
The effect
Each copy of the G allele carried 0.95 times the odds of Alzheimer's disease, proxy Alzheimer's disease or related dementias (95% confidence interval 0.93-0.96); p = 2 × 10−9.
How common The G allele had a frequency of about 13% in the people studied.
Where it sits Chromosome 2, band 2q33.2 — in an intron of CYP20A1.
What each result means
C/CNo copy of the version the research linked to Alzheimer's disease, proxy Alzheimer's disease or related dementias. This is the starting point the study compared everyone against.
C/GOne copy of the version the research linked to Alzheimer's disease, proxy Alzheimer's disease or related dementias. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Alzheimer's disease, proxy Alzheimer's disease or related dementias. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs115600411
What is rs115600411?
rs115600411 is a single position in the genome, in or near the CYP20A1 gene. Published research associates it with alzheimer's disease, proxy alzheimer's disease or related dementias. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs115600411 linked to?
On MyGeneLog this position is linked to Alzheimer's Disease. The research behind each link, and its sources, are set out on that condition page.
Does having rs115600411 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 rs115600411 come from?
GWAS Catalog, Nature genetics 2026, PMID:42237039. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
