Background: To examine whether polymorphisms in the VEGFA gene lead to low VEGFA production in peripheral blood and increased risk of NEC in the Chinese Han population. @@@ Material and methods: Thirty NEC patients and 80 control subjects were enrolled. Six VEGFA single-nucleotide polymorphisms (SNPs) were performed using the SEQUENOM MassARRAY platform assay. The concentration of VEGFA in the plasma was measured using an enzyme-linked immunosorbent assay. @@@ Results: The rs699947 and rs833061 VEGF-A SNPs were found to be associated with low plasma levels and high risk of NEC. @@@ Conclusion: Our results suggested that, if validated in larger studies, screening for VEGFA SNPs and plasma levels might be useful as a risk factor for NEC in the future.
