Who was studied 1,495,159 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0117 SD unit higher (95% confidence interval 0.0077-0.0157); p = 8 × 10−9.
How common The T allele had a frequency of about 17% in the people studied.
Where it sits Chromosome 16, band 16q23.1 — in an intron of VAT1L.
What each result means
C/CPublished research associates this genotype with typical/baseline likelihood of Refractive error — no copies of the reported risk allele.
C/TPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Refractive error.
T/TPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Refractive error compared to the general population.

Questions about rs67660447
What is rs67660447?
rs67660447 is a single position in the genome, in or near the VAT1L gene. Published research associates it with refractive error. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs67660447 linked to?
On MyGeneLog this position is linked to Myopia. The research behind each link, and its sources, are set out on that condition page.
Does having rs67660447 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 rs67660447 come from?
GWAS Catalog, Nature genetics 2026, PMID:42009823. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
