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 43,148 European ancestry individuals; replicated in 1,179 Central or South Asian individuals, 1,161 African ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.332 lower (95% confidence interval 0.25-0.41); p = 3 × 10−16.
How common The A allele had a frequency of about 27% in the people studied.
Where it sits Chromosome 18, band 18p11.32 — in an intron of COLEC12.
What each result means
A/ATwo copies of the version the research linked to Retinal thickness (pixel 119_175). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Retinal thickness (pixel 119_175). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Retinal thickness (pixel 119_175). This is the starting point the study compared everyone against.

Questions about rs17452020
What is rs17452020?
rs17452020 is a single position in the genome, in or near the COLEC12 gene. Published research associates it with retinal thickness (pixel 119_175). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs17452020 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 rs17452020 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.
