VEGFA and endometriosis: Such findings appear to be corroborated by other studies which evaluated the different VEGF SNPs independently from their effect on the risk of endometriosis in different populations, and found no significant associations with -2578C > A[16, 40], -460 T < C[16, 34, 40–48], +405G > C[16, 35, 40, 43, 44, 49, 50] or +936C < T[34, 35, 40, 51].
