Loop Mediated Isothermal Amplification: A Promising Tool for Screening Genetic Mutations

Abstract

Mutation screening is elemental for clinical diagnosis and in determining therapeutic strategies. Nucleic acid-based techniques are considered to be the most accurate tools in genetic diagnosis. One such technique is loop-mediated isothermal amplification (LAMP) assay, which has seen tremendous applications in recent years. The advantages of the assay lie in its rapidity, efficiency, sensitivity, and cost. It works in isothermal conditions and amplifies the target gene using DNA polymerases that have strand displacement activity. To date, the assay has been widely used in different fields of research, including pathogen detection, crop development, and disease diagnosis. However, despite the potential, its application in mutation screening has been minimal. This review highlights the LAMP assay and its variants that have been developed for screening single-nucleotide polymorphisms and gene translocations in cancer.
