Exon
Definition
Sequence retained in a mature transcript, which may be coding or untranslated. A transcript is an RNA product of transcription. Not every exon directly encodes protein. Changes in transcript abundance or structure also require assay-specific interpretation.
- Context
- Gene expression
For example, sequence retained in a mature transcript may be untranslated rather than part of the protein-coding reading frame.
