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 35,292 European ancestry individuals, 227 African ancestry individuals, 380 South Asian ancestry individuals, 115 East Asian ancestry individuals, 338 individuals.
The effect
Each copy of the A allele shifted the measure 28.8 lower (95% confidence interval 20.4-37.26); p = 2 × 10−11.
Where it sits Chromosome 1, band 1p34.1 — a missense change in MAST2.
What each result means
A/ATwo copies of the version the research linked to Whole amygdala volume. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Whole amygdala volume. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Whole amygdala volume. This is the starting point the study compared everyone against.

Questions about rs33931638
What is rs33931638?
rs33931638 is a single position in the genome, in or near the MAST2 gene. Published research associates it with whole amygdala volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs33931638 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 rs33931638 come from?
GWAS Catalog, Biological psychiatry 2024, PMID:37391117. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
