Abstract:
Objective To detect exon deletions/duplications in the DMD gene in Duchenne and Becker muscular dystrophy pedigrees using multiplex ligation-dependent probe amplification method,and explore the usefulness of multiplex ligation-dependent probe amplification analysis as a method for genetic diagnostics in patients with Duchenne and Becker muscular dystrophy.Methods Exon deletions/duplications in the DMD gene were analyzed by multiplex ligation-dependent probe amplification for two pedigrees with Duchenne muscular dystrophy and Becker muscular dystrophy.Patients and carriers were diagnosed by multiplex ligation-dependent probe amplification.Results The pedigree with Duchenne muscular dystrophy was caused by DelEx45-50 mutation,while the pedigree with Becker muscular dystrophy was caused by Dup Ex3-4 mutation.Patients and carriers were diagnosed by multiplex ligation-dependent probe amplification method.Conclusion Exon deletions/duplications in the DMD gene can be indicated by probe copies using multiplex ligation-dependent probe amplification method under standard operating procedure.Multiplex ligation-dependent probe amplification should be considered as a rapid and accurate clinical method for an initial mutation analysis of DMD gene with exon deletions/duplications.
