Who was studied 434,646 British ancestry individuals, 8,796 British Central/South Asian individuals, 6,573 British African individuals.
The effect
Each copy of the C allele shifted the measure 0.01 nm higher (95% confidence interval 0.01-0.01); p = 3 × 10−12.
Where it sits Chromosome 4, band 4q22.1 — in an intron of FAM13A.
What each result means
C/CTwo copies of the version the research linked to Average diameter for LDL particles. 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 Average diameter for LDL particles. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Average diameter for LDL particles. This is the starting point the study compared everyone against.

Questions about rs2869948
What is rs2869948?
rs2869948 is a single position in the genome, in or near the FAM13A gene. Published research associates it with average diameter for ldl particles. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs2869948 linked to?
On MyGeneLog this position is linked to Cholesterol (LDL, HDL and Total). The research behind each link, and its sources, are set out on that condition page.
Does having rs2869948 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 rs2869948 come from?
GWAS Catalog, Nature genetics 2025, PMID:41044249. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
