Who was studied 81,247 European ancestry individuals (MTAG effective sample size boosted by osteoarthritis, endometriosis and multiple sclerosis samples).
The effect
Each copy of the C allele shifted the measure 0.031 lower (95% confidence interval 0.021-0.041); p = 6 × 10−10.
How common The C allele had a frequency of about 34% in the people studied.
Where it sits Chromosome 2, band 2p16.1 — between genes, 1.9 kb from REL.
What each result means
C/CTwo copies of the version the research linked to Rheumatoid arthritis (MTAG). That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Rheumatoid arthritis (MTAG). That is a smaller link than two copies.
T/TNo copy of the version the research linked to Rheumatoid arthritis (MTAG). This is the starting point the study compared everyone against.

Questions about rs13026755
What is rs13026755?
rs13026755 is a single position in the genome, in or near the near REL gene. Published research associates it with rheumatoid arthritis (mtag). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13026755 linked to?
On MyGeneLog this position is linked to Rheumatoid Arthritis. The research behind each link, and its sources, are set out on that condition page.
Does having rs13026755 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 rs13026755 come from?
GWAS Catalog, Human reproduction (Oxford, England) 2025, PMID:40262193. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
