Abstract
Nearly all patients affected by myoclonic epilepsy with ragged-red fibres (MERRF) harbour a mutation in the mitochondrial transfer RNA(Lys) gene. We report on an 8-year-old girl with clinical and diagnostic features of MERRF. After excluding one of the common mutations associated with MERRF, a complete sequence analysis of the mitochondrial genome revealed an m.4284 G > A mutation in the mitochondrial transfer RNA(Ile) gene. This mutation has only once been described in a family with variable clinical symptoms, but has not yet been linked to MERRF. This case extends the mutational spectrum associated with the MERRF phenotype, and demonstrates the importance of performing a comprehensive mutational analysis in patients with suspected mitochondrial disease when common mutations have been ruled out.
