The effect
The reported allele is C; the catalogue records no effect size
; p = 7 × 10−10.
Where it sits Chromosome 19, band 19q13.32 — in an intron of NECTIN2.
What each result means
C/CTwo 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.
C/TOne copy of the version the research linked to Alzheimer's disease. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Alzheimer's disease. This is the starting point the study compared everyone against.

Questions about rs8105340
What is rs8105340?
rs8105340 is a single position in the genome, in or near the NECTIN2 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 rs8105340 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 rs8105340 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 rs8105340 come from?
GWAS Catalog, Alzheimer's & dementia : the journal of the Alzheimer's Association 2025, PMID:39998322. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
