Who was studied 405,540 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.00936 lower (95% confidence interval 0.0068-0.0119); p = 9 × 10−13.
How common The C allele had a frequency of about 61% in the people studied.
Where it sits Chromosome 15, band 15q26.1 — between genes, 7.9 kb from BLM.
What each result means
C/CTwo copies of the version the research linked to Height (baseline). That is the strongest link of the three results. A link in a study is not a diagnosis.
C/GOne copy of the version the research linked to Height (baseline). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Height (baseline). This is the starting point the study compared everyone against.

Questions about rs404623
What is rs404623?
rs404623 is a single position in the genome, in or near the near BLM gene. Published research associates it with height (baseline). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs404623 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 rs404623 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 rs404623 come from?
GWAS Catalog, Nature communications 2025, PMID:40374629. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
