Exon 174 occurs in the following Titin transcripts (the number indicates the exon rank of exon 174 in each transcript).
PSI: The "proportion spliced-in" (an estimate of the percentage of TTN transcripts that incorporate this exon based on RNAseq data) is 3% in DCM (LV tissue of 84 end-stage patients) and 10% in GTEx (LV tissue of 105 samples from Genotype-Tissue Expression project). (See Ref. 1 for details)
Symmetry: This exon is symmetric, i.e. the length of the exon is a multiple of three and therefore removal of it will not alter the reading frame.

No TTN truncating variants affecting this exon have been described in major published studies.
Size of Exon: 84 bases
