MLPA® probes

MLPA (Multiplex Ligation-dependent Probe Amplification) is a multiplex PCR method detecting abnormal copy numbers of up to 50 different genomic DNA or RNA sequences, which is able to distinguish sequences differing in only one nucleotide (1). The MLPA technique is easy to use and can be performed in many laboratories, as it only requires a thermocycler and capillary electrophoresis equipment. Up to 96 samples can be handled simultaneously, with results being available within 24 hours. Although for most hereditary conditions, (partial) gene deletions or duplications account for less than 10 % of all disease-causing mutations, for many other disorders this is 10 to 30 % or even higher still. The inclusion of MLPA in clinical settings can therefore significantly increase the detection rate of many genetic disorders.
