[i] ^aCDS represents distinct protein-coding sequences from the initiator methionine to the termination codon, including alternative splice forms.

[ii] ^bTranscripts include alternative 5′ and 3′ UTRs, with counts of each based on whether the underlying CDS has full support, partial support, or no support.

[iii] ^cNumber of transcripts in each class that have a 5′ UTR.

[iv] ^dNumber of transcripts that have a polyA_site or signal sequence ≤25 bp from transcript end.
