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 47,745 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.622 higher (95% confidence interval 0.48-0.76); p = 3 × 10−20.
How common The T allele had a frequency of about 0% in the people studied.
Where it sits Chromosome 21, band 21q21.1 — in an intron of NCAM2.
rs565689408 is a single position in the genome, in or near the NCAM2 gene. Published research associates it with ncam2 protein levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
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.
