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 Up to 6,000 African American ancestry individuals, 8,754 European ancestry individuals; replicated in At least 1,893 European ancestry individuals.

How common The A allele had a frequency of about 94% in the people studied.
Where it sits Chromosome 8, band 8p23.2 — in an intron of CSMD1.
rs77378271 is a single position in the genome, in or near the CSMD1 gene. Published research associates it with cannabis dependence symptom count. 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.
