Enzymatic mutation detection technologies.
Mutation is as necessary for life as fidelity is in DNA replication. The study of mutations reveals the normal functions of genes, messages, proteins, the causes of many diseases, and the variability of responses among individuals. Indeed, recent mutations that have not yet become polymorphisms are often deleterious and pertinent to the disease history of afflicted individuals. This review discusses the principles behind a variety of methods for the detection of mutations and factors that should be considered in future methods design. One enzymatic approach in particular using orthologs of the CEL I nuclease that show high specificity for all mismatches, appears to be easy and robust. Further developments of this and other methods will allow mutation detection to become an integral component of individualized medicine.
