Where this position leads
Condition: Alzheimer's Disease
What the study found
Who was studied 128,681 European ancestry cases, 849,833 European ancestry controls.
The effect Each copy of the T allele carried 0.96 times the odds of Alzheimer's disease, proxy Alzheimer's disease or related dementias (95% confidence interval 0.95-0.97); p = 5 × 10−9.
How common The T allele had a frequency of about 29% in the people studied.
Where it sits Chromosome 16, band 16p11.2 — in an intron of BCKDK.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
rs889555 is a single position in the genome, in or near the BCKDK 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.
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.
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.
