What each result means

C/C Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Blue vs. green eyes compared to the general population. (GWAS Catalog, Nat Genet 2008, PMID:18488028)

C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Blue vs. green eyes. (GWAS Catalog, Nat Genet 2008, PMID:18488028)

T/T Published research associates this genotype with typical/baseline likelihood of Blue vs. green eyes — no copies of the reported risk allele. (GWAS Catalog, Nat Genet 2008, PMID:18488028)

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.

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.
