The Asporin (ASPN) gene which encodes a protein of the extracellular cartilage matrix contains a triplet repeat encoding for aspartic acid (D) within exon 2 The D14 allele was found associated with knee and hip osteoarthritis in case-control study in the Japanese population. Genotyping Greek knee OA patients for the D repeats we determined that the D15 allele could be considered a risk allele for our population. © 2005 OsteoArthritis Research Society International. ER -
