Forty per cent of patients with mitochondrial myopathies, a diverse group of multisystem diseases predominantly affecting skeletal muscle and the brain, have large deletions of a proportion of muscle mitochondrial DNA (mt DNA). These appeared to be identical in 13 of 28 cases, contained within the region 828613595 bp. Analysis of the deletion junction in two cases showed a 13 nucleotide sequence which occurred in the normal genome as a direct repeat flanking the region deleted in the mutant mt DNAs. Mt DNA deletions may arise from recombination or slippage between short sequence repeats during replication.
