GCK · rs2070971
Where this position leads
Condition: Age-Related Macular Degeneration
Strength of the evidence
Its strongest genetic-study result is p = 10−32, with 47 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 98,316 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.0043 higher (95% confidence interval 0.0028-0.0058); p = 9 × 10−9.
How common The T allele had a frequency of about 14% in the people studied.
Where it sits Chromosome 7, band 7p13 — in an intron of GCK.

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.

rs2070971 is a single position in the genome, in or near the GCK gene. Published research associates it with triglycerides in very large vldl. 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 Age-Related Macular Degeneration. 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.
