From: Sequence features responsible for intron retention in human
Lengths of flanking exons, retained introns and "exon + retained intron + exon" units. Panel (A) Distribution of lengths of upstream exons flanking the retained intron (B) Distribution of lengths of downstream exons flanking the retained intron. Data set used in (A) and (B):1193 low and 98 high-RIF exon pairs with both upstream and downstream splice borders defined by introns. (C) Distribution of lengths of retained introns. (D) Distribution of lengths of retained intron + flanking exons. Only units composed by internal exons were considered.
