Abstract

OBJECTIVE:

To investigate the correlations between three vascular endothelial growth factor 2 (VEGFR2) gene polymorphisms, +1192C>T, +1719T>A, and -604T>C, and deep venous thrombosis (DVT) in Chinese Han population.

METHODS:

We conducted a case-control study, between September 2009 and September 2012, in a Chinese Han population with onset of lower extremity DVT. A total of 135 patients were enrolled in the case group and 156 healthy individuals in the control group. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotype and allele frequencies of the VEGFR2 gene polymorphisms +1192C>T, +1719T>A, and -604T>C. Haplotype analyses were conducted with SHEsis program. Logistic regression was used to detect the risk factors of DVT. Outpatient review and telephone follow-up were conducted to analyze the long-term treatment of DVT patients.

RESULTS:

The allele and genotype frequencies of -604T>C VEGFR2 polymorphism exhibited significant differences between the case and control groups (both p < 0.05). Haplotype analyses showed remarkable differences between the case and control groups in the distribution frequency of TAC and CTT haplotypes in the VEGFR2 gene (both p < 0.05). Logistic regression analysis showed independent correlation between the incidence of DVT and TAC haplotype in the VEGFR2 gene (p < 0.05). In addition, the TAC haplotype may be a risk factor for DVT treatment failure.

CONCLUSION:

Our findings suggest that the VEGFR2 gene -604T>C polymorphism and TAC haplotype are associated with DVT, and the TAC haplotype might affect the efficacy of long-term treatment of DVT patients.
