Multiple mitochondrial dysfunctions syndrome type 4
Synonyms: MMDS4
A rare severe genetic neurometabolic disease characterized by infantile-onset of progressive neurodevelopmental regression optic atrophy with nystagmus and diffuse white matter disease. Affected individuals usually have central hypotonia that progresses to limb spasticity and hyperreflexia eventually resulting in a vegetative state. Recurrent chest infections are frequently associated and seizures (usually generalized tonic-clonic) may occasionally be observed. Brain magnetic resonance imaging shows diffuse bilateral symmetric abnormalities in the cerebral periventricular white matter with variable lesions in other areas but sparing the basal ganglia.
