Abstract:
We report a new case of MERRF (myoclonus epilepsy with ragged red fibers) syndrome with basal nuclei calcification on the brain CT scan, without hormonal abnormalities, with high CSF protein and hyperlactacidemia, juvenile onset and death at 18 years. Biochemical study of mitochondrial muscle enzymes showed decreased NADH-cytochrome-C-reductase and Succinate-cytochrome C-reductase activity, suggesting a Complex III defect of the respiratory chain. Similar reported cases are reviewed.
