What the study found

Who was studied 1,400,535 European ancestry, East Asian ancestry, Hispanic or Latin American, African ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0076 lower (95% confidence interval 0.0052-0.01); p = 3 × 10−10.

How common The A allele had a frequency of about 58% in the people studied.

Where it sits Chromosome 1, band 1q23.3 — in an intron of NOS1AP.

What each result means

A/A Two copies of the version the research linked to Smoking cessation. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Smoking cessation. That is a smaller link than two copies.
G/G No copy of the version the research linked to Smoking cessation. This is the starting point the study compared everyone against.

Questions about rs4657158

What is rs4657158?

rs4657158 is a single position in the genome, in or near the NOS1AP gene. Published research associates it with smoking cessation. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does rs4657158 affect how medicines work?

NOS1AP carries pharmacogenomic findings for QT-prolonging medicines. That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.

Does having rs4657158 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 rs4657158 come from?

GWAS Catalog, Nature 2022, PMID:36477530. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
