  • Title: Designing a simple multiplex ligation-dependent probe amplification (MLPA) assay for rapid detection of copy number variants in the genome.
    Author: Shen Y, Wu BL.
    Journal: J Genet Genomics; 2009 Apr; 36(4):257-65. PubMed ID: 19376486.
    Abstract:
    Copy number variants (CNVs) are pervasive in the human genome and are responsible for many Mendelian diseases and genomic disorders. The detection of CNVs is an essential element of a complete mutation screening strategy. Many techniques have been developed for gene dosage testing. Multiplex ligation-dependent probe amplification (MLPA) is a robust, easy and flexible technique that can detect both deletions and duplications for more than 40 loci in one assay. It has been widely used in research and diagnostic laboratories. We routinely develop our own MLPA assays for quick validation of array comparative genomic hybridization (CGH) findings. Here we discuss the general principles and critical aspects of MLPA assay development and validation using all synthetic MLPA probes. We believe that MLPA will play important roles in the rapid detection of genomic disorders associated with genomic imbalances, the confirmation of pathogenic mutations involving exonic deletions/duplications, CNV genotyping and population frequency analysis of CNVs.
