Abstract The genetic background of rheumatoid arthritis RA is only partly understood and several genes seem to be involved. The matrix metalloproteinases MMP1 interstitial collagenase and MMP3 stromelysin 1 are thought to be important in destructive joint changes seen in RA. In the present study functional relevant promoter polymorphisms of MMP1 and MMP3 were genotyped in 308 patients and in 110 controls to test whether the polymorphisms contribute to the severity of the disease measured by radiographic progression of joint destruction. For comparison the shared epitope of HLA DR4 and DR1 SE was determined by polymerase chain reaction. There was no association of MMP polymorphisms with susceptibility to RA. However a strong linkage disequilibrium was observed between the 1G 2G MmPi and the 5A 6A MMP3 polymorphisms P 10-6 linkage disequilibrium index D . .
