Smoking initiation

near CACNA1G · rs17717246

What the study found

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

The effect Each copy of the C allele shifted the measure 0.0081 lower (95% confidence interval 0.0063-0.0099); p = 5 × 10−19.

How common The C allele had a frequency of about 35% in the people studied.

Where it sits Chromosome 17, band 17q21.33 — between genes, 0.9 kb from CACNA1G.

What each result means

C/C 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.
C/T One copy of the version the research linked to Smoking initiation. That is a smaller link than two copies.
T/T No copy of the version the research linked to Smoking initiation. This is the starting point the study compared everyone against.

Questions about rs17717246

What is rs17717246?

rs17717246 is a single position in the genome, in or near the near CACNA1G 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 rs17717246 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 rs17717246 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.
