Abstract

Vascular endothelial growth factor-A (VEGFA) is normally expressed at high levels in the human placenta, and lower levels have been observed in placental tissue of women with recurrent pregnancy loss. The objective of this study was to determine if genetic polymorphisms in the VEGFA gene associated with altered gene expression play a role in some cases of recurrent pregnancy loss (RPL). A case-control study of 99 women with RPL and 181 fertile controls was performed evaluating four common VEGFA polymorphisms associated with altered gene expression (-2578 C/A, -1154 G/A, -634 G/C, and +936 C/T). The allele frequency of the -2578 A allele was lower among women with RPL compared to fertile controls (0.39 vs. 0.48, p=0.049), while the allele frequency of the -634 C allele was higher among women with RPL compared to fertile controls (0.39 vs. 0.29, p=0.020). Women with RPL and controls had similar allele frequencies for the -1154 and +936 minor alleles. We conclude that some allelic polymorphisms associated with altered expression of VEGFA are more common among women with RPL compared to fertile controls.
