Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 4,759 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.372 lower (95% confidence interval 0.27-0.47); p = 2 × 10−13.
How common The C allele had a frequency of about 29% in the people studied.
Where it sits Chromosome 2, band 2p13.1 — in the 3′ untranslated region of STAMBP.
What each result means
C/CTwo copies of the version the research linked to Blood alliin levels. 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 Blood alliin levels. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Blood alliin levels. This is the starting point the study compared everyone against.

Questions about rs3813230
What is rs3813230?
rs3813230 is a single position in the genome, in or near the STAMBP gene. Published research associates it with blood alliin levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs3813230 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 rs3813230 come from?
GWAS Catalog, Genome biology 2026, PMID:42426908. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
