Pitfalls of Multiple Ligation-Dependent Probe Amplifications in Detecting DMD Exon Deletions or Duplications
Multiple ligation-dependent probe amplifications (MLPAs) are a key technology for the molecular diagnosis of Duchenne/Becker muscular dystrophy, which is mainly caused by large gene arrangements. However, little is known about the false-positive rates of MLPA for this disease. Here, we review MLPA analysis results from 398 patients suspected to have Duchenne/Becker muscular dystrophy. MLPA assay was used for screening the entire coding region. If these amplifications produced normal results, direct sequencing was performed to search for sequence variations and to determine single-exon deletions, duplications, or indeterminate results.
