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 20,692 European ancestry cases, 434,472 European ancestry controls.
The effect
Each copy of the T allele shifted the measure 1.04 lower (95% confidence interval 0.8-1.28); p = 4 × 10−17.
How common The T allele had a frequency of about 0% in the people studied.
Where it sits Chromosome 16, band 16q24.3 — inside TUBB3.
What each result means
C/CNo copy of the version the research linked to Hair colour (natural, before greying): Red (UKB data field 1747_2). This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Hair colour (natural, before greying): Red (UKB data field 1747_2). That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Hair colour (natural, before greying): Red (UKB data field 1747_2). That is the strongest link of the three results. A link in a study is not a diagnosis.
rs139107291 is a single position in the genome, in or near the TUBB3 gene. Published research associates it with hair colour (natural, before greying): red (ukb data field 1747_2). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs139107291 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 rs139107291 come from?
GWAS Catalog, Nature genetics 2021, PMID:34737426. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
