Schematic representation of experimentally confirmed human CD44 pre-mRNA and respective isoforms. Blue filled boxes represent constant region exons, while white filled boxes represent exons of the variable region present in the designated CD44 isoform. Dark blue filled boxes with reduced box size represent truncated exons from the constant region. The blue line represents missing exon(s). Exon 18, filled black, contains an early 3’UTR and only makes part of CD44st isoform
