near RNU6-366P · rs139844049

What the study found

Who was studied 51,424 European ancestry cases, 403,740 European ancestry controls.

The effect Each copy of the C allele shifted the measure 0.35 higher (95% confidence interval 0.26-0.44); p = 2 × 10−15.

How common The C allele had a frequency of about 1% in the people studied.

Where it sits Chromosome 14, band 14q32.12 — between genes, 22.2 kb from RNU6-366P.

What each result means

A/A No copy of the version the research linked to Hair colour (natural, before greying): Blonde (UKB data field 1747_1). This is the starting point the study compared everyone against.
A/C One copy of the version the research linked to Hair colour (natural, before greying): Blonde (UKB data field 1747_1). That is a smaller link than two copies.
C/C Two copies of the version the research linked to Hair colour (natural, before greying): Blonde (UKB data field 1747_1). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs139844049

What is rs139844049?

rs139844049 is a single position in the genome, in or near the near RNU6-366P gene. Published research associates it with hair colour (natural, before greying): blonde (ukb data field 1747_1). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs139844049 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 rs139844049 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.
