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 2,584 European ancestry individuals with chronic obstructive pulmonary disease, 3,002 European ancestry healthy individuals, 343 African American individuals with chronic obstructive pulmonary disease, 1,006 African American healthy individuals.
The effect Each copy of the G allele shifted the measure 0.13 lower (95% confidence interval 0.09-0.17); p = 3 × 10−10.
How common The G allele had a frequency of about 37% in the people studied.
Where it sits Chromosome 15, band 15q25.1 — in an intron of CHRNA3.
rs112878080 is a single position in the genome, in or near the CHRNA3 gene. Published research associates it with diffusing capacity of carbon monoxide. 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.
