Association of a BMP9 haplotype with ossification of the posterior longitudinal ligament (OPLL) in a Chinese population.

ABSTRACT: Direct or ex vivo BMP9 adenoviral gene therapy can induce massive bone formation at the injection sites and clearly promote spinal fusion. A comprehensive analysis of the osteogenic activity indicated that BMP9 was one of the most potent inducers of osteogenic differentiation both in vitro and in vivo among 14 types of human BMPs. However, genetic variations and whether they correlated with OPLL were not considered. We have sequenced the complete BMP9 gene in 450 patients with OPLL and in 550 matched controls. Analyses were performed on single markers and haplotypes. Single marker tests identified 6 SNPs, among which the minor alleles of rs7923671 (T>C; P=0.0026; OR: 1.33, CI: 1.10-1.60), rs75024165 (C>T, Thr304Met; P<0.001; OR: 1.76, CI: 1.47-2.12) and rs34379100 (A>C; P<0.001; OR: 1.52,
