Аннотация
BACKGROUND: Complex I deficiency is the most common energy generation disorder which may clinically present at any age with a wide spectrum of symptoms and signs. The T10158C mutation ND3 gene is rare and occurs in patients showing an early rapid neurological deterioration invariably leading to death after a few months.
CASE PRESENTATION: We report a 9year-old boy with a mtDNA T10158C mutation showing a mild MELAS-like phenotype and brain MRI features congruent with both MELAS and Leigh syndrome. Epilepsia partialis continua also occurred in the clinical course and related to a mild cortical atrophy of the left perisylvian area.
DISCUSSION: The present case confirms that the clinical spectrum of Complex I deficiency related to T10158C mutation ND3 gene is wider than previously described. Our observation further suggests that testing mutation in the MT-ND3 gene should be included in the diagnostic work-up of patients presenting with epilepsia partialis continua accompanied by suspicion of mitochondrial disorder.
