Smoking initiation

PHC2 · rs55745410

What the study found

Who was studied 2,669,029 European ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.0102 lower (95% confidence interval 0.0084-0.012); p = 1 × 10−29.

How common The G allele had a frequency of about 36% in the people studied.

Where it sits Chromosome 1, band 1p35.1 — in an intron of PHC2.

What each result means

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

Questions about rs55745410

What is rs55745410?

rs55745410 is a single position in the genome, in or near the PHC2 gene. Published research associates it with smoking initiation. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs55745410 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 rs55745410 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.
