Mouse Vasp, Evl and Enah gene structure. Vasp, Evl and Enah have thirteen exons in common. The Evl gene has one exon in addition that can be alternatively included (exon 10a; previous name exon I). The Enah gene is more complex and has a longer exon 5, an extra expressed exon (Enah exon 6) and four alternatively included exons (exons 3a, 3b, 6L (a longer form of exon 6) and 11a; previous names +++ or INV, ++, + and 11a, respectively) and one alternatively excluded intron (intron S). An exon numbering is proposed for the alternatively included exons. The previously used exon names are also indicated.
