Standard

Platelet distribution width

DOCK8 · rs116920018

Strength of the evidence

2 / 4

Its strongest genetic-study result is p = 10−36, with 4 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 408,112 British individuals.

The effect Each copy of the G allele shifted the measure 0.209 higher (95% confidence interval 0.18-0.24); p = 3 × 10−36.

How common The G allele had a frequency of about 0% in the people studied.

Where it sits Chromosome 9, band 9p24.3 — a missense change in DOCK8.

What ClinVar records

Classification Conflicting classifications of pathogenicity for Combined immunodeficiency due to DOCK8 deficiency, DOCK8-related disorder, Intellectual disability, Ovarian serous cystadenocarcinoma, Thymoma and 4 more; criteria provided, conflicting classifications (1 of 4 stars, 13 submitters), last evaluated 2026-02-02.

Change history MyGeneLog™ keeps a copy of every weekly release from 2026-10-19 and compares them. This position's classification has not changed since.

What this is ClinVar's aggregate record for this position (as of its 2026-11-01 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

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