We give an overview of current methods for the detection of point mutations as well as small insertions and deletions in clinical diagnostics. For each method, the following characteristics are specified: (a) principle, (b) major modifications, (c) maximum fragment size that can be analyzed, (d) ratio and type of mutations that can be detected, (e) minimum ratio of mutant to wild-type alleles at which mutations can be detected, and (f) detection methods. Special attention is paid to the possibilities of quality assessment and the potential for standardization and automation.
