[Name] CD79B-006 [Transcript ID] ENST00000583260 [bp] 433 [Protein] No protein [Translation ID] - [CCDS] - [UniProt] - [RefSeq] - [Flags] 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.TSL:NA [Biotype] 
Alternatively spliced transcript that is believed to contain intronic sequence relative to other coding transcripts in a given locus.Retained intron
