Introduction: The matrilin-3 polymorphism T298M has been described to be associated with hand osteoarthritis in the carpometacarpal joint 1 (CMC1) and with spinal disc degeneration. In vitro studies revealed that expression levels, processing and secretion of matrilin-3 T298M were similar to the wt protein. Structural analysis indicated an impact on the formation of collagen II/IX/XI heterofibrils, whereas the binding to collagen was not affected. We have now generate...
