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 47,637 European ancestry cases, 1,422,823 European ancestry controls.
The effect
Each copy of the A allele carried 1.06 times the odds of Ambidextrousness; p = 5 × 10−10.
How common The A allele had a frequency of about 65% in the people studied.
Where it sits Chromosome 7, band 7q21.2 — in an intron of ANKIB1.
What each result means
A/ATwo copies of the version the research linked to Ambidextrousness. 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 Ambidextrousness. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Ambidextrousness. This is the starting point the study compared everyone against.
rs2040498 is a single position in the genome, in or near the ANKIB1 gene. Published research associates it with ambidextrousness. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs2040498 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 rs2040498 come from?
GWAS Catalog, Nature human behaviour 2021, PMID:32989287. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
