Where this position leads
Condition: Eye Color and Pigmentation
Strength of the evidence
Its strongest genetic-study result is p = 10−9, with 1 associations in the GWAS Catalog.
4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.
What the study found
Who was studied 4,987 Iberian ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.486 higher (95% confidence interval 0.33-0.65); p = 3 × 10−9.
How common The T allele had a frequency of about 2% in the people studied.
Where it sits Chromosome 15, band 15q13.1 — in an intron of HERC2.
rs556360317 is a single position in the genome, in or near the HERC2 gene. Published research associates it with eye color. 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 Eye Color and Pigmentation. The research behind each link, and its sources, are set out on that condition page.
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.
