F. Scaglia et al., Mitochondrial DNA depletion associated with partial complex II and IV deficiencies and 3-methylglutaconic aciduria, J CHILD NEU, 16(2), 2001, pp. 136-138
We report a patient with mitochondrial DNA depletion, partial complex II an
d IV deficiencies, and 3-methylglutaconic aciduria. Complex II deficiency h
as not been previously observed in mitochondrial DNA depletion syndromes. T
he observation of 3-methylglutaconic and 3-methylglutaric acidurias may be
a useful indicator of a defect in respiratory chain function caused by mito
chondrial DNA depletion.
