[Detection of mutations causing Duchenne and Becker muscular dystrophies: multiplex polymerase chain reaction vs. Multiplex ligation dependent probe amplification].
Revista Peruana de Medicina Experimental y Salud Pública(2019)
Abstract
Duchenne and Becker muscular dystrophies are rare diseases that receive limited attention in our field. The objective of this study was to implement the Multiplex Ligation-dependent Probe Amplification technique (MLPA) and to demonstrate that it has advantages over the Multiplex Polymerase Chain Reaction (Multiplex PCR) technique. Samples from 40 individuals with a presumptive diagnosis of Duchenne and Becker muscular dystrophies were analyzed: first by Multiplex PCR and then by MLPA. Fifteen individuals with causal deletions were detected with Multiplex PCR, while the MLPA technique was able to diagnose 21 individuals, four duplications, and 17 deletions. In conclusion, the MLPA technique can detect mutations of the exon deletion and duplication type, yielding a larger number of molecular diagnoses due to alterations in the DMD gene.
