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 A allele shifted the measure 0.01 mmol/L lower (95% confidence interval 0.01-0.01); p = 7 × 10−12.
Where it sits Chromosome 19, band 19p13.3 — in an intron of NFIC.
What each result means
A/ATwo copies of the version the research linked to Cholesterol in Medium HDL. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Cholesterol in Medium HDL. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Cholesterol in Medium HDL. This is the starting point the study compared everyone against.

Questions about rs12975319
What is rs12975319?
rs12975319 is a single position in the genome, in or near the NFIC gene. Published research associates it with cholesterol in medium hdl. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs12975319 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 rs12975319 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 rs12975319 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.
