Standard

Mean spheric corpuscular volume

ANK1 · rs7823698

Strength of the evidence

3 / 4

Its strongest genetic-study result is p = 10−62, with 3 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 0.079 lower (95% confidence interval 0.07-0.088); p = 7 × 10−63.

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

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

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