Who was studied 394,642 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.0148 lower (95% confidence interval 0.011-0.018); p = 4 × 10−17.
How common The C allele had a frequency of about 50% in the people studied.
Where it sits Chromosome 7, band 7q34 — in the 3′ untranslated region of ZC3HAV1.
What each result means
C/CTwo copies of the version the research linked to Platelet crit (UKB data field 30090). 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 Platelet crit (UKB data field 30090). That is a smaller link than two copies.
T/TNo copy of the version the research linked to Platelet crit (UKB data field 30090). This is the starting point the study compared everyone against.

Questions about rs7803490
What is rs7803490?
rs7803490 is a single position in the genome, in or near the ZC3HAV1 gene. Published research associates it with platelet crit (ukb data field 30090). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs7803490 linked to?
On MyGeneLog this position is linked to Celiac Disease. The research behind each link, and its sources, are set out on that condition page.
Does having rs7803490 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 rs7803490 come from?
GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
