Impact of common SNPs in VEGF gene on the susceptibility of osteosarcoma.

We conducted a case-control study to assess the role of vascular endothelial growth factor (VEGF) -634G/C, +936C/T, and +1612G/A genetic variations in the development of osteosarcoma in a Chinese population. This hospital-based case-control study examined 130 patients with osteosarcoma and 130 age- and gender-matched healthy controls from March 2011 and March 2013. Polymerase chain reaction-restriction fragment length polymorphism was applied to assess the VEGF -634G/C, +936C/T, and +1612G/A gene polymorphisms. Using conditional regression analysis, individuals carrying the TT genotype of VEGF +936C/T were found to be correlated with an elevated risk of osteosarcoma, with an adjusted odds ratio (95% confidence interval) of 2.70 (1.02-8.28). In conclusion, our study suggests that the TT genotype of VEGF +936C/T genetic variants is associated with an increased risk of osteosarcoma.
