Strength of the evidence

2 / 4

Its strongest genetic-study result is p = 10−43, 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 153,950 Korean ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0342 lower (95% confidence interval 0.029-0.039); p = 2 × 10−43.

How common The T allele had a frequency of about 34% in the people studied.

Where it sits Chromosome 2, band 2p13.2 — in an intron of ZNF638.

What each result means

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

Questions about rs6740645

What is rs6740645?

rs6740645 is a single position in the genome, in or near the ZNF638 gene. Published research associates it with height. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs6740645 linked to?

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

Does having rs6740645 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 rs6740645 come from?

GWAS Catalog, Nature communications 2025, PMID:40436827. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
