Where this position leads
Condition: Educational Attainment
Strength of the evidence
Its strongest genetic-study result is p = 10−308, with 10 associations in the GWAS Catalog.
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 1,311,438 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.0188 higher (95% confidence interval 0.014-0.024); p = 2 × 10−15.
How common The T allele had a frequency of about 8% in the people studied.
Where it sits Chromosome 16, band 16q24.3 — a missense change in MC1R.

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 2026-10-19 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.

rs1805008 is a single position in the genome, in or near the MC1R gene. Published research associates it with educational attainment (mtag). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Educational Attainment. The research behind each link, and its sources, are set out on that condition page.
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
