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 1,495,159 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0177 SD unit higher (95% confidence interval 0.013-0.022); p = 9 × 10−15.
How common The T allele had a frequency of about 87% in the people studied.
Where it sits Chromosome 14, band 14q22.1 — in an intron of NIN.
What each result means
G/GNo copy of the version the research linked to Refractive error. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Refractive error. That is a smaller link than two copies.
T/TTwo 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.

Questions about rs55984715
What is rs55984715?
rs55984715 is a single position in the genome, in or near the NIN 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 rs55984715 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 rs55984715 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.
