Genome-Wide Data-Mining of Candidate Human Splice Translational Efficiency Polymorphisms (STEPs) and an Online Database
A. Boxes are exonic and lines are intronic. Vertical bands denote splice site motif regions where a STEP may occur. A shows a standard splice form with a single intron. B shows partial intron retention or extension of either exon, as well as exon skipping. C shows full intron retention. D shows an upstream exon activated by a splice site.
