The effect
The reported allele is C; the catalogue records no effect size
; p = 1 × 10−8.
Where it sits Chromosome 9, band 9p13.1 — between genes, 5.6 kb from FAM240B.
What each result means
C/CTwo copies of the version the research linked to Alzheimer's disease or family history of Alzheimer's disease. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/GOne copy of the version the research linked to Alzheimer's disease or family history of Alzheimer's disease. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Alzheimer's disease or family history of Alzheimer's disease. This is the starting point the study compared everyone against.

Questions about rs1203948313
What is rs1203948313?
rs1203948313 is a single position in the genome, in or near the near FAM240B gene. Published research associates it with alzheimer's disease or family history of 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 rs1203948313 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 rs1203948313 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 rs1203948313 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.
