Sections within genes that are included in the final processed mRNA and include the protein-coding sequences.
Use in clinical context
Exons contain information that directly results in the final order of amino acids within the protein. Interspersed between exons are introns which are removed during protein synthesis in a process known as splicing. Changes in the exon sequence can result in changes to the amino acid sequence and resulting protein.
