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 up to 1,359,002 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.00911 higher (95% confidence interval 0.0063-0.012); p = 3 × 10⁻¹⁰.

How common The T allele had a frequency of about 17% in the people studied.

Where it sits Chromosome 13, band 13q21.33 — between genes, 33.4 kb from ZDHHC20P4.

What each result means

A/A 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.

A/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 rs71427690

What is rs71427690?

rs71427690 is a single position in the genome, in or near the near ZDHHC20P4 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.

Does having rs71427690 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 rs71427690 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.
