Transcript Support Level 1, when transcripts are supported by at least one non-suspect mRNA.

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).APPRIS P1

PRINCIPAL1 - APPRIS candidate principal isoform.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods.
