Overview
Mutation detection encompasses the laboratory methods used to identify changes in DNA sequence, ranging from single-base substitutions and small insertions or deletions to larger structural rearrangements within genes and chromosomes. The goal is to determine whether a sample carries a variant relative to a reference sequence and, increasingly, to quantify the proportion of mutant molecules present. Established approaches include direct Sanger sequencing, allele-specific and quantitative PCR, restriction-fragment analysis, high-resolution melting, and screening of defined exons for known polymorphisms, while next-generation sequencing now permits comprehensive variant calling across many loci. Sensitive techniques such as digital PCR enable absolute quantification of rare alleles, supporting detection of low-frequency mutations and circulating nucleic acids. Accurate mutation detection underpins the diagnosis of inherited metabolic disorders, the characterization of disease-associated alleles, pharmacogenetic testing, and the molecular workup of cancer, where somatic mutations guide prognosis and targeted therapy. It also informs studies of molecular evolution and sequence variation in pathogens. Key considerations include analytical sensitivity and specificity, limit of detection, distinction of true variants from sequencing artifacts, and confirmation by an independent method. Reliable interpretation requires careful reference comparison, appropriate controls, and an understanding of each platform's error profile.
