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 65,680 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0116 lower (95% confidence interval 0.0087-0.0145); p = 2 × 10−15.
How common The A allele had a frequency of about 94% in the people studied.
Where it sits Chromosome 3, band 3p13 — in an intron of FOXP1.
What each result means
A/ATwo copies of the version the research linked to Vertical cup-disc ratio. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/TOne copy of the version the research linked to Vertical cup-disc ratio. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Vertical cup-disc ratio. This is the starting point the study compared everyone against.
American journal of human genetics · 2021 · PMID 34077760 · open access
Questions about rs77877421
What is rs77877421?
rs77877421 is a single position in the genome, in or near the FOXP1 gene. Published research associates it with vertical cup-disc ratio. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs77877421 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 rs77877421 come from?
GWAS Catalog, American journal of human genetics 2021, PMID:34077760. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
