TSL 2: A transcript where the best supporting mRNA is flagged as suspect or the support is from multiple ESTs

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.

TSL 5: A transcript where no single transcript supports the model structure.
