VEGFA SNPs (rs34357231 and rs35569395) alleles (I, D, and D′) identified within the electropherograms from the direct DNA sequencing data. The reference sequence NM_00117626 contains the 18-bp inserted (I) allele while the rs34357231 SNP illustrates a D allele and the rs35569395 SNP illustrates a D′ allele each having an 18-bp deletion. The difference between the two deletion alleles results from whether the deleted sequence contains two G nucleotides on the 3′ sequence (rs34357231) or on the 5′ sequence (rs35569394)
