APPRIS P3: Where the APPRIS core modules are unable to choose a clear principal variant and there more than one of the variants have distinct CCDS identifiers, APPRIS selects the variant with lowest CCDS identifier as the principal variant. The lower the CCDS identifier, the earlier it was annotated.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.

TSL 3: A transcript where the only support is from a single EST

The Transcript Support Level (TSL) is a method to highlight the well-supported and poorly-supported transcript models for users, based on the type and quality of the alignments used to annotate the transcript.

APPRIS ALT1: For genes in which the APPRIS core modules are unable to choose a clear principal isoform, the ALT1 is the candidate transcript(s) models that is conserved in at least three tested species.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.

TSL 1: A transcript where all splice junctions are supported by at least one non-suspect mRNA.
