Transcript Support Level Not Analysed. Pseudogenes, single exon transcripts, HLA, T-cell receptor and Ig transcripts are not analysed and therefore not given any of the TSL categories.

The Transcript Support Level (TSL) is a method to highlight the well-supported and poorly-supported transcript models for users. The method relies on the primary data that can support full-length transcript structure: mRNA and EST alignments supplied by UCSC and Ensembl.

GENCODE basicThe GENCODE set is the gene set for human and mouse. GENCODE Basic is a subset of representative transcripts (splice variants).
