text: Multiplex ligation-dependent probe amplification was invented by  Jan Schouten, a Dutch scientist. The method was first described in 2002 in the scientific journal Nucleic Acid Research. The first applications included the detection of exon deletions in the human genes BRCA1, MSH2 and MLH1, which are linked to hereditary breast and colon cancer. Now MLPA is used to detect hundreds of hereditary disorders, as well as for tumour profiling.
