Left-handedness

TUBA1B · rs11168884

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 1,766,671 European ancestry individuals.

The effect Each copy of the T allele carried 0.98 times the odds of Left-handedness; p = 2 × 10⁻¹⁰.

How common The T allele had a frequency of about 34% in the people studied.

Where it sits Chromosome 12, band 12q13.12 — in an intron of TUBA1B-AS1.

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 rs11168884

What is rs11168884?

rs11168884 is a single position in the genome, in or near the TUBA1B 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 rs11168884 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 rs11168884 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.
