Novel NDUFS4 gene mutation in an atypical late-onset mitochondrial form of multifocal dystonia

Mitochondrial complex I, the largest component of the mitochondrial respiratory chain, comprises 44 subunits of which 7 are encoded by the mitochondrial genome and the remainder by the nuclear genome. Isolated complex I deficiencies represent a major contribution within the group of respiratory chain defects. We report an atypical case carrying a homozygous NDUFS4 missense mutation, with late-o...

Novel mitochondrial transfer RNA(Phe) gene mutation associated with late-onset neuromuscular disease.

BACKGROUND An extensive range of molecular defects have been identified in the human mitochondrial genome (mitochondrial DNA); many are associated with well-characterized, progressive neurological syndromes, but a minority of patients have uncharacteristic phenotypes in which symptoms may be relatively mild. OBJECTIVE To describe a novel transfer RNA(Phe) mutation of mitochondrial DNA in a la...

Childhood-Onset Progressive Dystonia With Mitochondrial DNA G14459A Mutation

This article reports the case of an 11-year-old boy with progressive dystonia caused by the homoplasmic G14459A mitochondrial DNA mutation. The patient presented with focal dystonia in the right upper limb at 3 years of age, which progressed over 4 years to exhibit dystonia in both the upper and lower limbs. At 7 years of age, high signal intensity lesions in the bilateral striata and the midbr...

Functional characterization of the c.462delA mutation in the NDUFS4 subunit gene of mitochondrial complex I.

To the Editor : Isolated deficiency of complex I (CI) is the most commonly identified biochemical defect in childhoodonset mitochondrial diseases (1). Approximately 50% of CI-deficient individuals exhibit Leigh syndrome (LS) or Leigh-like syndrome, a devastating neurodegenerative disorder characterized by specific neuroradiological and neuropathological features. Although CI deficiency has been...

Maternally transmitted late-onset non-syndromic deafness is associated with the novel heteroplasmic T12201C mutation in the mitochondrial tRNAHis gene.

The authors report here the clinical, genetic, molecular and biochemical characterisation of a large five-generation Han Chinese pedigree with maternally transmitted non-syndromic hearing loss. 17 of 35 matrilineal relatives exhibited variable severity and age at onset of sensorineural hearing loss. The average age at onset of hearing loss in matrilineal relatives of this family is 29 years, wh...
