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 40,456 European ancestry current smokers, 13,511 African American current smokers, 2,920 Hispanic current smokers, 59,056 European ancestry mostly never smokers, 17,751 African American mostly never smokers, 7,195 Hispanic mostly never smokers.
The effect
The reported allele is T; the catalogue records no effect size
; p = 9 × 10−10.
Where it sits Chromosome 1, band 1p35.3 — in an intron of PHACTR4.
What each result means
C/CNo copy of the version the research linked to Smoking status (current vs never). This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Smoking status (current vs never). That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Smoking status (current vs never). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs61783804
What is rs61783804?
rs61783804 is a single position in the genome, in or near the PHACTR4 gene. Published research associates it with smoking status (current vs never). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs61783804 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 rs61783804 come from?
GWAS Catalog, Nature communications 2020, PMID:33082346. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
