Corpus callosum mean thickness

GATAD2B · rs9427220

What the study found

Who was studied 46,685 European ancestry individuals; replicated in 4,765 non-European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0376 lower (95% confidence interval 0.027-0.049); p = 3 × 10−11.

How common The A allele had a frequency of about 44% in the people studied.

Where it sits Chromosome 1, band 1q21.3 — inside GATAD2B.

What each result means

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

Questions about rs9427220

What is rs9427220?

rs9427220 is a single position in the genome, in or near the GATAD2B gene. Published research associates it with corpus callosum mean thickness. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs9427220 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 rs9427220 come from?

GWAS Catalog, Nature communications 2025, PMID:41188267. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
