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 38,977 European ancestry, East Asian ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.0511 higher (95% confidence interval 0.037-0.065); p = 2 × 10−12.
How common The G allele had a frequency of about 49% in the people studied.
Where it sits Chromosome 9, band 9q33.1 — in an intron of ASTN2.
What each result means
A/ANo copy of the version the research linked to Hippocampal subfield left CA3 volume (head). This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to Hippocampal subfield left CA3 volume (head). That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Hippocampal subfield left CA3 volume (head). That is the strongest link of the three results. A link in a study is not a diagnosis.
rs6478240 is a single position in the genome, in or near the ASTN2 gene. Published research associates it with hippocampal subfield left ca3 volume (head). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs6478240 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 rs6478240 come from?
GWAS Catalog, Nature genetics 2023, PMID:37337106. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
