Relationship between VEGFA polymorphisms and serum VEGF protein levels and recurrent spontaneous miscarriage

Reduced VEGF secretion, and specific VEGFA variants may contribute to the pathogenesis of RSM. However, the association of VEGFA SNPs with RSM appears to be independent of their association with altered VEGF serum levels. The differential association of VEGFA variants with RSM is in line with previous findings on the contribution of ethnicity/racial background to genetic association studies.
