PURPOSE: To investigate whether rs11190870 near LBX1 correlates with the susceptibility or curve progression of adolescent idiopathic scoliosis (AIS) in a Han Chinese population. METHODS: A total of 949 AIS patients and 976 age-matched healthy controls were recruited. All the subjects were genotyped using the PCR-based invader assay. Case-control study and case-only study were performed to define the contribution of rs11190870 to predisposition and curve severity of AIS. Additionally, we further conducted a meta-analysis of the study findings together with those of previously reported studies. RESULTS: A significant association of rs11190870 with AIS was observed in the Han Chinese population (P = 1.8 × 10(-9); odd ratio = 1.51; 95 % confidence interval = 1.33-1.71), and AIS patients with TT genotype had a larger Cobb angle than those with TC or CC genotype (P = 0.005). The meta-analysis confirmed that the positive association of this SNP with AIS in the East Asian population. CONCLUSIONS: The SNP rs11190870 near LBX1 is associated with both susceptibility and curve progression of AIS.
