Where this position leads

What the study found

Who was studied 161,228 European ancestry cases, 965,985 European ancestry controls, 5,433 East Asian ancestry cases, 126,769 East Asian ancestry controls, 3,463 African or African American cases, 21,448 African or African American controls, 993 South Asian ancestry cases, 18,871 South Asian ancestry controls, 523 Hispanic cases, 2,903 Hispanic controls, 616 Admixed ancestry cases, 8,268 Admixed ancestry controls.

The effect Each copy of the C allele carried 0.95 times the odds of Knee osteoarthritis (95% confidence interval 0.931428665239036-0.965253683630557); p = 6 × 10⁻⁹.

How common The C allele had a frequency of about 94% in the people studied.

Where it sits Chromosome 6, band 6p21.1 — in an intron of MDFI.

What each result means

C/C Two copies of the version the research linked to Knee osteoarthritis. That is the strongest link of the three results. A link in a study is not a diagnosis.

C/G One copy of the version the research linked to Knee osteoarthritis. That is a smaller link than two copies.

G/G No copy of the version the research linked to Knee osteoarthritis. This is the starting point the study compared everyone against.

Questions about rs1555156

What is rs1555156?

rs1555156 is a single position in the genome, in or near the MDFI gene. Published research associates it with knee osteoarthritis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs1555156 linked to?

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

Does having rs1555156 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 rs1555156 come from?

GWAS Catalog, Nature 2025, PMID:40205036. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
