Examples

  • The patient has a missense mutation that resulted in a significant change in the protein's structure.

  • Researchers discovered a specific missense mutation that changes one amino acid, affecting the protein's function.

  • It was therefore of interest to examine the cellular phenotype of the E424K missense mutant and compare it to that of the null mutant.

    Academic text (2016)
  • Recently, three individuals were reported to have one of two different heterozygous missense mutations in PLIN1, which altered the amino acids in the carboxy terminus of the protein.

Morphology

missense = sense (semi-transparent) = mis + sense

The word is formed from mis- + sense, but the specialized genetic meaning is not fully predictable from the everyday meaning of the parts.

Etymology

Missense comes from the parts mis- ('wrong'), the same mis- in mistake, and sense ('meaning'). So a missense mutation is a 'wrong meaning' in the DNA code that leads to a different amino acid in the protein.
