Missense single nucleotide polymorphism of the ADAM12 gene is associated with radiographic knee osteoarthritis in middle-aged Estonian cohort
چکیده انگلیسی

SummaryObjectiveOne of the recognized candidate genes of osteoarthritis (OA) is the ADAM metallopeptidase domain 12 (meltrin alpha) gene. We investigated the potential role of two single nucleotide polymorphisms (SNP) of the ADAM12 gene in susceptibility to radiographic knee OA and its progression in an Estonian cohort.MethodsThe rs3740199 and rs1871054 polymorphisms were genotyped according to restriction fragment polymorphism in a population-based cohort consisting of 189 subjects selected from the age group 32–55 years. The radiological features of OA were measured in the tibio- and patellofemoral joints (PFJ). The X-ray investigation was repeated 3 years later for estimation of OA progression.ResultsWe found statistically significant association between rs3740199 polymorphism and patellofemoral OA in male patients (P = 0.014), genetic risk was mostly related to CC homozygosity. The same SNP also affected the presence of advanced grade (II + III) osteophytes in the whole group (P = 0.042) and the occurrence of osteophytes on the patellar margins in the PFJ (P = 0.046). In OA progression the most significant association was found between joint space narrowing of the tibiofemoral joint and rs3740199 SNP in women (P = 0.018). The rs1871054 polymorphism was not related to OA susceptibility or to progression traits. In our study the haplotype GC (rs3740199/rs1871054) was associated with reduced risk for development of osteophytes in the PFJ (P = 0.041).ConclusionsWe conclude that rs3740199 polymorphism may affect occurrence of knee OA and its progression. We also hypothesize that the genetic contribution of ADAM12 to OA is remarkably gender-dependent and anatomical site-specific.
