Neonatal presentation of coenzyme Q10 deficiency
We report a neonate with ubiquinone deficiency. Skeletal muscle analysis revealed
markedly diminished mitochondrial complex II+ III activity that could be restored by addition
of a ubiquinone analogue. Ubiquinone deficiency was confirmed by high-performance liquid
chromatography. Oral ubiquinone therapy was not associated with clinical improvement; the
patient died at 2 years.(J Pediatr 2001; 139: 456-8)
