title: Genotype-phenotype correlation in the 5703G>A mutation in the tRNA(ASN) gene of mitochondrial DNA.
abstract: The 5703G>A mutation in the tRNA gene of mitochondrial DNA seems to show a tissue-specific phenotype: early age of clinical presentation, progressive external ophthalmoplegia, fatigability and 'extremely thin appearance'. We report a second patient with the same mutation and phenotype.
