Among these 9 genes, vascular endothelial zinc finger 1 (VEZF1) encodes the Krüppel-like zinc finger protein, which plays an important role in vascular development and can inhibit the expression of antiangiogenic factor Cited2 in endothelial cells, providing a biological target for the diagnosis and treatment of AAA [35]. Here, VEZF1 is linked to triple-A syndrome.
