Biliary atresia (BA) is a neonatal disease characterized by chronic inflammation of the bile ducts and progressive aggravation of jaundice, but with a poor prognosis and high mortality. The etiology of BA is still uncertain which may be related to gene defect, virus infection, immune disorder, gene polymorphism. As a proinflammatory cytokine, VEGFA gene polymorphism (rs3025039) has been shown to be related to the pathogenesis of BA in Taiwanese population.


We investigated the association between VEGFA gene polymorphism (rs3025039) and BA susceptibility using the largest case-control cohort, totaling with 506 BA patients and 1473 healthy controls in a Southern Chinese Han population. VEGFA gene polymorphism (rs3025039) was genotyped using the MassARRAY iPLEX Gold system (Sequenom). Odds ratios (OR) and 95% confidence intervals (CIs) were used to access the association between the VEGFA gene polymorphism (rs3025039) and BA risk.


No significant association was found between the VEGFA gene polymorphism (rs3025039) and BA risk in the overall analysis.


These results suggest that VEGFA gene polymorphism (rs3025039) may not be associated with the risk of BA in the Southern Chinese Han population.
