Alternative splicing (AS) affects up to 95% of multi-exonic genes in humans (Pan et al., 2008). The three main types of AS are exon skipping, alternative 5′ or 3′ usage and intron retention (IR). IR occurs when an intron is transcribed into pre-mRNA and remains in the final mRNA. It constitutes a class of AS that is often neglected because these events are difficult to measure reliably.
