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 5,130 Icelandic individuals; replicated in 3,330 European ancestry individuals.
The effect
Each copy of the C allele carried 1.40 times the odds of Blue vs. green eyes (95% confidence interval 1.25-1.57); p = 6 × 10−17.
How common The C allele had a frequency of about 75% in the people studied.
Where it sits Chromosome 9, band 9p23 — in an intron of LURAP1L-AS1.
What each result means
C/CTwo copies of the version the research linked to Blue vs. green eyes. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Blue vs. green eyes. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Blue vs. green eyes. This is the starting point the study compared everyone against.
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.
Questions about rs1408799
What is rs1408799?
rs1408799 is a single position in the genome, in or near the TYRP1 gene. Published research associates it with blue vs. green eyes. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What do people read about alongside rs1408799?
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.
Does having rs1408799 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 rs1408799 come from?
GWAS Catalog, Nat Genet 2008, PMID:18488028. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
