Multiplex Ligation-dependent Probe Amplification (MLPA)
Majority of the genetic disease have been associated with abnormality in genomic DNA (gDNA) not restricted to mutations. In some cases, diseases have been associated with deletion or duplication of genes such as in case of Duchenne Muscular Dystrophy (DMD). To properly characterize the disease phenotype genotype correlation ones need not only to detect the associated mutation but also the deletion and duplication with the gene of interest. Among many available techniques for detecting the deletion and duplication within a gene, MLPA is one the most cost-effective, robust test method with shortest test reporting time. In addition it has the ability to detect small rearrangements and copy number variations (CNV). The input DNA amount can as low as 50 ng per reaction.
MLPA is basically an advance version of multiplex polymerase chain reaction having the ability to amplify and quantify multiple targets (upto 60 specific nuclei acid sequence) in single tube. Fragment analysis of the amplified product is carried by capillary electrophoresis (Gold Standard in Sequencing) and compared to the reference.
