Standard

Collagen alpha-2(VI) chain levels

COL6A2 · rs35548026

Strength of the evidence

3 / 4

Its strongest genetic-study result is p = 10−102, 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 10,708 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.493 lower (95% confidence interval 0.45-0.54); p = 3 × 10−102.

How common The A allele had a frequency of about 9% in the people studied.

Where it sits Chromosome 21, band 21q22.3 — a missense change in COL6A2.

What ClinVar records

Classification Benign/Likely benign for Bethlem myopathy 1A; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 13 submitters), last evaluated 2026-02-03. ClinVar record 93948 NM_001849.4(COL6A2):c.2803G>A (p.Gly935Arg)

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 2026-11-09 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 Collagen alpha-2(VI) chain levels. 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 Collagen alpha-2(VI) chain levels. That is a smaller link than two copies.
G/G No copy of the version the research linked to Collagen alpha-2(VI) chain levels. This is the starting point the study compared everyone against.
