VEGFA and lymphedema: The aim of this study is a comparative analysis of polymorphismof genes of vascular endothelial growth factor and its receptors together with genes of matrix metalloproteinasesin two forms of lymphedema, analysis of the relationshipof polymorphism of these genes with the level of vascularendothelial growth factor and matrix metalloproteinasesandtheir inhibitors in blood serum and affected tissues.
