Standard

Hair colour (natural, before greying): Red (UKB data field 1747_2)

near CBFA2T3 · rs530238572

Strength of the evidence

3 / 4

Its strongest genetic-study result is p = 10−94, 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 20,692 European ancestry cases, 434,472 European ancestry controls.

The effect Each copy of the C allele shifted the measure 2.83 higher (95% confidence interval 2.56-3.1); p = 4 × 10−95.

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

Where it sits Chromosome 16, band 16q24.3 — between genes, 11.4 kb from CBFA2T3.

What each result means

C/C Two copies of the version the research linked to Hair colour (natural, before greying): Red (UKB data field 1747_2). That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to Hair colour (natural, before greying): Red (UKB data field 1747_2). That is a smaller link than two copies.
T/T No copy of the version the research linked to Hair colour (natural, before greying): Red (UKB data field 1747_2). This is the starting point the study compared everyone against.
