Left-handedness

WASF3 · rs9581731

What the study found

Who was studied 1,766,671 European ancestry individuals.

The effect Each copy of the T allele carried 0.98 times the odds of Left-handedness; p = 1 × 10−9.

How common The T allele had a frequency of about 71% in the people studied.

Where it sits Chromosome 13, band 13q12.13 — between genes, 31.6 kb from WASF3.

What each result means

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

Questions about rs9581731

What is rs9581731?

rs9581731 is a single position in the genome, in or near the WASF3 gene. Published research associates it with left-handedness. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs9581731 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 rs9581731 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.
