Leber plus disease
MONDO:0020478Leber `plus' disease describes patients with the clinical features of Leber's hereditary optic neuropathy (LHON) in combination with other serious systemic or neurological abnormalities. These abnormalities include: postural tremor, motor disorder, multiple sclerosis-like syndrome, spinal cord disease, skeletal changes, Parkinsonism with dystonia, anarthria, dystonia, motor and sensory peripheral neuropathy, spasticity and mild encephalopathy. It is caused by maternally-inherited mitochondrial DNA (mtDNA) mutations.
Also known as: LHON plus disease
