Who was studied 341,805 European ancestry individuals, 6,006 African ancestry individuals, 7,316 South Asian ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.0159 lower (95% confidence interval 0.011-0.021); p = 2 × 10−9.
Where it sits Chromosome 1, band 1p31.3 — in the 3′ untranslated region of AK4.
What each result means
C/CTwo copies of the version the research linked to C-reactive protein levels. 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 C-reactive protein levels. That is a smaller link than two copies.
G/GNo copy of the version the research linked to C-reactive protein levels. This is the starting point the study compared everyone against.

Questions about rs1855981
What is rs1855981?
rs1855981 is a single position in the genome, in or near the AK4 gene. Published research associates it with c-reactive protein levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs1855981 linked to?
On MyGeneLog this position is linked to C-Reactive Protein Levels. The research behind each link, and its sources, are set out on that condition page.
Does having rs1855981 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 rs1855981 come from?
GWAS Catalog, Nature genetics 2021, PMID:33462484. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
