Who was studied 74,124 European ancestry type 2 diabetes cases, 102,084 European ancestry migraine cases, 1,595,263 European ancestry controls.
The effect
The reported allele is T; the catalogue records no effect size
; p = 1 × 10−8.
Where it sits Chromosome 20, band 20q13.33 — between genes, 3.9 kb from C20orf181.
What each result means
C/CNo copy of the version the research linked to Migraine or type 2 diabetes. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Migraine or type 2 diabetes. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Migraine or type 2 diabetes. That is the strongest link of the three results. A link in a study is not a diagnosis.
rs4809370 is a single position in the genome, in or near the near C20orf181 gene. Published research associates it with migraine or type 2 diabetes. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs4809370 linked to?
On MyGeneLog this position is linked to Type 2 Diabetes. The research behind each link, and its sources, are set out on that condition page.
Does having rs4809370 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 rs4809370 come from?
GWAS Catalog, Genes 2022, PMID:36292730. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
