Who was studied 10,094 European ancestry current and former smoker individuals, 3,260 African American current and former smoker individuals, 178 current and former smoker individuals.
The effect
Each copy of the C allele shifted the measure 0.016 lower (95% confidence interval -); p = 4 × 10−16.
How common The C allele had a frequency of about 64% in the people studied.
Where it sits Chromosome 4, band 4q31.21 — in an intron of LOC105377462.
What each result means
C/CTwo copies of the version the research linked to Post bronchodilator FEV1/FVC ratio. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/GOne copy of the version the research linked to Post bronchodilator FEV1/FVC ratio. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Post bronchodilator FEV1/FVC ratio. This is the starting point the study compared everyone against.
rs1813903 is a single position in the genome, in or near the near HHIP gene. Published research associates it with post bronchodilator fev1/fvc ratio. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs1813903 linked to?
On MyGeneLog this position is linked to Chronic Obstructive Pulmonary Disease (COPD), Pulmonary Function (Lung Capacity). The research behind each link, and its sources, are set out on that condition page.
Does having rs1813903 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 rs1813903 come from?
GWAS Catalog, BMC Genet 2015, PMID:26634245. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
