Standard

Platelet distribution width

WAS · rs146220228

Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−8, 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 408,112 British individuals.

The effect Each copy of the A allele shifted the measure 0.106 lower (95% confidence interval 0.07-0.142); p = 7 × 10−9.

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

Where it sits Chromosome X, band Xp11.23 — a missense change in WAS.

What ClinVar records

Classification Conflicting classifications of pathogenicity for X-linked severe congenital neutropenia, Thrombocytopenia 1, Wiskott-Aldrich syndrome, WAS-related disorder; criteria provided, conflicting classifications (1 of 4 stars, 13 submitters), last evaluated 2026-06-01. ClinVar record 135413 NM_000377.3(WAS):c.391G>A (p.Glu131Lys)

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