Papers in Europe PMC whose title or abstract names both this rsID and that subject. A shared paper means somebody wrote about the two together — it is not a claim that this position explains the subject.
rs17646946 is a single position in the genome, in or near the TCHH gene. Published research associates it with common traits (other). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Hair Color. The research behind each link, and its sources, are set out on that condition page.
Subjects that appear in the title or abstract of the same papers as this rsID include skin, sun and hair (1 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.
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.
