Standard

Smoking initiation

CNNM2 · rs7087040

Strength of the evidence

3 / 4

Its strongest genetic-study result is p = 10−64, with 1 associations in the GWAS Catalog.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What the study found

Who was studied 3,382,012 European ancestry, East Asian ancestry, Hispanic or Latin American, African ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0143 higher (95% confidence interval 0.013-0.016); p = 8 × 10−65.

How common The A allele had a frequency of about 30% in the people studied.

Where it sits Chromosome 10, band 10q24.32 — in an intron of CNNM2.

What each result means

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