Combined oxidative phosphorylation defect type 4

Combined oxidative phosphorylation defect type 4 is a rare mitochondrial disorder due to a defect in mitochondrial protein synthesis characterized by a neonatal onset of severe metabolic acidosis and respiratory distress, persistent lactic acidosis with episodes of metabolic crises, developmental regression, microcephaly, abnormal gaze fixation and pursuit, axial hypotonia with limb spasticity and reduced spontaneous movements. Neuroimaging studies reveal polymicrogyria, white matter abnormalities and multiple cystic brain lesions, including basal ganglia, and cerebral atrophy. Decreased activity of complex I and IV have been determined in muscle biopsy.

Also known as: COXPD4, TUFM combined oxidative phosphorylation deficiency, combined oxidative phosphorylation defect type 4, combined oxidative phosphorylation deficiency caused by mutation in TUFM, combined oxidative phosphorylation deficiency type 4, combined oxidative phosphorylation deficiency 4
