Titin has multiple isoforms, the longest being the theoretical IC (inferred complete) isoform which contains all 363 in-frame titin exons. Here all isoform positions have been mapped onto the IC sequence, with an exception being the C-terminal of the much shorter novex-3 isoform. This contains the out of frame exon 48 which cannot be mapped to the other isoforms.
