A GeneSNPs view of E2F2 (E2F Elongation Factor 2). E2F2 represents an average of the genes scanned for polymorphism discovery based on its size and nucleotide diversity. E2F2 has seven exons (depicted by light blue rectangles for coding and green for untranslated [UTR] sequences in the mRNA). For this gene, 24 kb was scanned for polymorphisms, which includes sequences 5′ to the first exon (∼1.7 kb) and 3′ of the last exon (∼1 kb) by amplifying 90 DNA samples using 34 overlapping amplicons (horizontal yellow bars above the gene structure). Vertical descending lines indicate the position of the SNPs identified in this sequence. The length of the vertical lines represents the frequency of the minor allele, and the color indicates whether the SNP location is in flanking (black), intronic (brown), synonymous (yellow), nonsynonymous (red), or UTR (green) sequences.
