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 each result means
A/A
Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Corneal structure compared to the general population. (GWAS Catalog, Nat Genet 2013, PMID:23291589)
A/G
Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Corneal structure. (GWAS Catalog, Nat Genet 2013, PMID:23291589)
G/G
Published research associates this genotype with typical/baseline likelihood of Corneal structure — no copies of the reported risk allele. (GWAS Catalog, Nat Genet 2013, PMID:23291589)

Questions about rs4938174
What is rs4938174?
rs4938174 is a single position in the genome, in or near the ARHGAP20 gene. Published research associates it with corneal structure. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs4938174 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 rs4938174 come from?
GWAS Catalog, Nat Genet 2013, PMID:23291589. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
