Smoking initiation (ever regular vs never regular) (MTAG)

PCCA-DT · rs9557376

Where this position leads

Condition: Smoking Behaviour and Nicotine Dependence

What the study found

Who was studied up to 1,359,002 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0105 higher (95% confidence interval 0.0081-0.0129); p = 1 × 10⁻¹⁷.

How common The T allele had a frequency of about 26% in the people studied.

Where it sits Chromosome 13, band 13q32.3 — in an intron of PCCA-DT.

What each result means

C/C No copy of the version the research linked to Smoking initiation (ever regular vs never regular) (MTAG). This is the starting point the study compared everyone against.

C/T One copy of the version the research linked to Smoking initiation (ever regular vs never regular) (MTAG). That is a smaller link than two copies.

T/T Two copies of the version the research linked to Smoking initiation (ever regular vs never regular) (MTAG). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs9557376

What is rs9557376?

rs9557376 is a single position in the genome, in or near the PCCA-DT gene. Published research associates it with smoking initiation (ever regular vs never regular) (mtag). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs9557376 linked to?

On MyGeneLog this position is linked to Smoking Behaviour and Nicotine Dependence. The research behind each link, and its sources, are set out on that condition page.

Does having rs9557376 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 rs9557376 come from?

GWAS Catalog, Nature genetics 2019, PMID:30643251. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
