ABSTRACT
Objective Two autosomal recessive forms of muscular dystrophyLGMD2B and Miyoshi myopathy may be indused by dysferlin gene mutation.The purpose of this study was to define molecular defects in dysferlin gene in a family with Miyoshi myopathy.Methods mRNA from peripheral blood in a Chinese Miyoshi myopathy pedigree was amplified by RT-PCR and the mutation was determined by sequencing the amplified products.Results The results of sequencing revealed a novel homozygous mutation,a 6429delG,on exon 53 of the dysferlin gene for the patients.Conclusion The 6429delG mutation in the dysferlin gene of patients creates a frameshift mutation which induces a stop codon at 2035 on exon 54 and the premature dysferlin contributes to the Miyoshi myopathy in the Chinese pedigree.
