Polymorphisms in ADAMTS4 and ADAMTS5 are not linked to susceptibility to knee osteoarthritis in the Turkish population

Description
Summary:Considering the functions of aggrecanase-1 (ADAMTS4) and -2 (ADAMTS5), which are thought to be the two major enzymes responsible for the destruction of aggrecans in arthritic diseases, we investigated whether important polymorphisms in the ADAMTS4 and ADAMTS5 genes affect osteoarthritis (OA) susceptibility. Our study took place in Mugla, Turkey. Ninety-five cases were recruited following OA diagnosis (72 women and 23 men), and 80 individuals without any symptoms or radiographic signs of OA (56 women and 24 men) were chosen as healthy controls. After obtaining DNA from patients and control subjects, ADAMTS4 and ADAMTS5 genotypes were determined using the ABI Prism StepOnePlus Real-Time system. In addition, we categorized patients based on OA grade. There were no significant differences in the genotype distributions of the four polymorphisms between the groups (P > 0.05). Moreover, ADAMTS4 and ADAMTS5 allele frequencies did not differ between OA and control participants (P > 0.05). These findings suggest that the ADAMTS4 (rs4233367 and rs11807350) and ADAMTS5 (rs226794 and rs2830585) variants examined may not contribute to susceptibility to knee OA in the Turkish population. Other gene polymorphisms should be assessed in order to explain variations in OA susceptibility.
