Standard

Insomnia

DOCK4 · rs3801781

Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−7, 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 593,724 European ancestry cases, 1,771,286 European ancestry controls.

The effect Each copy of the C allele shifted the measure 0.005 lower (95% confidence interval 0.003-0.007); p = 4 × 10−8.

Where it sits Chromosome 7, band 7q31.1 — in a non-coding transcript of DOCK4.

What each result means

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