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 475,645 European ancestry individuals, 8,590 African ancestry individuals, 85,279 East Asian ancestry individuals, 4,270 South Asian ancestry individuals, 14,668 Hispanic or Latin American individuals.

The effect Each copy of the T allele shifted the measure 11.4 z score higher; p = 7 × 10⁻³⁰.

How common The T allele had a frequency of about 77% in the people studied.

Where it sits Chromosome 21, band 21q22.11 — in an intron of KCNE2.

What each result means

C/C No copy of the version the research linked to Lung function (FEV1/FVC). This is the starting point the study compared everyone against.

C/T One copy of the version the research linked to Lung function (FEV1/FVC). That is a smaller link than two copies.

T/T Two copies of the version the research linked to Lung function (FEV1/FVC). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs743339

What is rs743339?

rs743339 is a single position in the genome, in or near the KCNE2 gene. Published research associates it with lung function (fev1/fvc). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs743339 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 rs743339 come from?

GWAS Catalog, Nature genetics 2023, PMID:36914875. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
