Refractive error

HAPLN4 · rs56144632

What the study found

Who was studied 1,495,159 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0271 SD unit lower (95% confidence interval 0.023-0.031); p = 3 × 10−34.

How common The A allele had a frequency of about 13% in the people studied.

Where it sits Chromosome 19, band 19p13.11 — in the 3′ untranslated region of HAPLN4.

What each result means

A/A Two copies of the version the research linked to Refractive error. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Refractive error. That is a smaller link than two copies.
G/G No copy of the version the research linked to Refractive error. This is the starting point the study compared everyone against.

Questions about rs56144632

What is rs56144632?

rs56144632 is a single position in the genome, in or near the HAPLN4 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.

Does having rs56144632 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 rs56144632 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.
