Brooks, Wisniewski, and Brown described a familial presentation of severe developmental retardation, speech delay, static encephalopathy with atrophic hydrocephalus, microcephaly, progressive spastic diplegia, a characteristic facial appearance, optic atrophy, and growth retardation associated with hypoplastic corpus callosum in one of the patients. The authors postulated a distinct X-linked mental retardation syndrome. Later on a similar phenotype was observed in three male siblings with an early lethal outcome. Here we describe three patients with several overlapping features and a progressive neurological picture presenting with a significantly compromised mitochondrial oxidative phosphorylation measured in a fresh muscle biopsy. Neurological deterioration is a commonly observed feature in mitochondrial disorders. Based on the unique combination of the clinical symptoms, we suggest that our patients have the Brooks-Wisniewski-Brown syndrome.
