Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 201,533 European ancestry cases, 901,637 European ancestry controls, 5,506 East Asian ancestry cases, 126,769 East Asian ancestry controls, 4,149 African or African American cases, 21,448 African or African American controls, 1,087 South Asian ancestry cases, 18,871 South Asian ancestry controls, 842 Hispanic cases, 3,489 Hispanic controls, 722 Admixed ancestry cases, 8,268 Admixed ancestry controls.
The effect
Each copy of the A allele carried 0.96 times the odds of Osteoarthritis of the hip or knee (95% confidence interval 0.950278841582603-0.969087685958702); p = 1 × 10−16.
How common The A allele had a frequency of about 20% in the people studied.
Where it sits Chromosome 9, band 9q33.1 — in an intron of PAPPA.
What each result means
A/A
Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Osteoarthritis of the hip or knee compared to the general population.
A/G
Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Osteoarthritis of the hip or knee.
G/G
Published research associates this genotype with typical/baseline likelihood of Osteoarthritis of the hip or knee — no copies of the reported risk allele.

Questions about rs7020944
What is rs7020944?
rs7020944 is a single position in the genome, in or near the PAPPA gene. Published research associates it with osteoarthritis of the hip or knee. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs7020944 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 rs7020944 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.
