Who was studied 10,450 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 4.1 lower (95% confidence interval 3.67-4.53); p = 5 × 10−77.
Where it sits Chromosome 16, band 16q24.3 — in an intron of DBNDD1.
What each result means
C/CNo copy of the version the research linked to Red vs. brown/black hair color. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Red vs. brown/black hair color. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Red vs. brown/black hair color. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs77381714
What is rs77381714?
rs77381714 is a single position in the genome, in or near the DBNDD1 gene. Published research associates it with red vs. brown/black hair color. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs77381714 linked to?
On MyGeneLog this position is linked to Hair Color. The research behind each link, and its sources, are set out on that condition page.
Does having rs77381714 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 rs77381714 come from?
GWAS Catalog, Communications biology 2021, PMID:34737440. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
