Standard

Insomnia

PTPRD · rs56288028

Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−12, with 2 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 A allele shifted the measure 0.012 lower (95% confidence interval 0.0081-0.0159); p = 6 × 10−13.

Where it sits Chromosome 9, band 9p24.1 — in an intron of PTPRD.

What each result means

A/A 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.
A/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.
