Description : Leigh syndrome is an early-onset progressive neurodegenerative disorder with a characteristic
neuropathology consisting of focal, bilateral lesions in one or more areas of the
central nervous system, including the brainstem, thalamus, basal ganglia, cerebellum,
and spinal cord. The lesions are areas of demyelination, gliosis, necrosis, spongiosis,
or capillary proliferation. Clinical symptoms depend on which areas of the central
nervous system are involved. The most common underlying cause is a defect in oxidative
phosphorylation (Dahl, 1998). Leigh syndrome may be a feature of a deficiency of any
of the mitochondrial respiratory chain complexes: complex I deficiency (252010), complex
II deficiency (252011), complex III deficiency (124000), complex IV deficiency (cytochrome
c oxidase; 220110), or complex V deficiency (604273).;
