Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−7, with 1 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 1,495,159 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.00974 SD unit higher (95% confidence interval 0.0063-0.0132); p = 4 × 10−8.

How common The T allele had a frequency of about 24% in the people studied.

Where it sits Chromosome 15, band 15q26.3 — in the 3′ untranslated region of IGF1R.

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.

What each result means

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

Questions about rs2684786

What is rs2684786?

rs2684786 is a single position in the genome, in or near the IGF1R gene. Published research associates it with refractive error. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs2684786 linked to?

On MyGeneLog this position is linked to Myopia. The research behind each link, and its sources, are set out on that condition page.

Does having rs2684786 mean I will get this?

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.

Where does the information about rs2684786 come from?

GWAS Catalog, Nature genetics 2026, PMID:42009823. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
