Who was studied 575,531 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.022 lower (95% confidence interval 0.016-0.028); p = 1 × 10−18.
Where it sits Chromosome 7, band 7p22.3 — a missense change in CYP2W1.
What each result means
C/CNo copy of the version the research linked to C-reactive protein levels. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to C-reactive protein levels. That is a smaller link than two copies.
T/TTwo 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.

Questions about rs3808348
What is rs3808348?
rs3808348 is a single position in the genome, in or near the CYP2W1 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 rs3808348 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 rs3808348 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 rs3808348 come from?
GWAS Catalog, Nature communications 2022, PMID:35459240. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
