Examples of alternative splicing detected using exon-level analysis of RNA - Seq counts in PIGQ (top panel) and VIM (bottom panel). X axis shows genomic location of exons (red and black dots for cases and controls, respectively) in hg18 coordinates. Y axis shows mean-subtracted normalized RNA-Seq read counts for each exon. Arrows at bottom right show direction of transcription. Neither gene was differentially expressed when all exons were considered together.
