NCI: A point mutation occurring within the protein-coding region of a gene, and which codes for a stop that can truncate the protein.,NCI: A mutation that alters the genetic code in a way that causes the premature termination of a protein. The altered protein may be partially or completely inactivated, resulting in a change or loss of protein function.,MSH: A mutation that converts a sense codon (CODON) into a stop codon (CODON, TERMINATOR) or an unassigned codon and leads to the formation of truncated proteins.
