Retinal thickness (functional principal component 4)

DIRC3 · rs2568177

What the study found

Who was studied 43,151 European ancestry individuals; replicated in 1,179 Central or South Asian individuals, 1,161 African ancestry individuals.

The effect Each copy of the G allele shifted the measure 23.6 lower (95% confidence interval 18.27-28.91); p = 4 × 10−18.

How common The G allele had a frequency of about 20% in the people studied.

Where it sits Chromosome 2, band 2q35 — in an intron of DIRC3.

What each result means

A/A No copy of the version the research linked to Retinal thickness (functional principal component 4). This is the starting point the study compared everyone against.
A/G One copy of the version the research linked to Retinal thickness (functional principal component 4). That is a smaller link than two copies.
G/G Two copies of the version the research linked to Retinal thickness (functional principal component 4). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs2568177

What is rs2568177?

rs2568177 is a single position in the genome, in or near the DIRC3 gene. Published research associates it with retinal thickness (functional principal component 4). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs2568177 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 rs2568177 come from?

GWAS Catalog, Nature communications 2025, PMID:39904976. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
