Sammanfattning (abstract):
Iron-sulphur cluster deficiency myopathy is caused by a deep intronic mutation in ISCU resulting in inclusion of a cryptic exon in the mature mRNA. ISCU encodes the iron-sulphur cluster assembly protein IscU. Iron-sulphur clusters are essential for most basic redox transformations including the respiratory-chain function. Most patients are homozygous for the mutation with a phenotype characterized by a non-progressive myopathy with childhood onset of early fatigue, dyspnoea and palpitation on trivial exercise. A more severe phenotype with early onset of a slowly progressive severe muscle weakness, severe exercise intolerance and cardiomyopathy is caused by a missense mutation in compound with the intronic mutation. Treatment of cultured fibroblasts derived from three homozygous patients with an antisense phosphorodiamidate morpholino oligonucleotide for 48 h resulted in 100% restoration of the normal splicing pattern. The restoration was stable and after 21 days the correctly spliced mRNA still was the dominating RNA species.
