PURPOSE OF REVIEW: The first reports published in 2010 on enzyme replacement therapy in late-onset Pompe disease (LOPD) allow us now to stand back and adapt the strategies. In the meantime, substantial progress has been made in basic and applied research on animal models to enhance the efficacy of treatments. This brief review highlights the...

Isolated cytochrome c oxidase (COX) deficiency (MIM#220110) is a relatively common biochemical finding in pediatric patients with mitochondrial disorder. It has been associated with different clinical phenotypes ranging from isolated myopathy to severe multisystem disorder. It is a genetically heterogeneous trait, and the most frequent genetic...

Coenzyme Q(10) (CoQ(10)) deficiency has been associated with an increasing number of clinical phenotypes. Whereas primary CoQ(10) defects are related to mutations in ubiquinone biosynthetic genes, which are now being unraveled, and respond well to CoQ(10) supplementation, the etiologies, and clinical phenotypes related to secondary deficiencies...

ObjectiveTo identify the genetic and epigenetic defects in patients presenting with a facioscapulohumeral (FSHD) clinical phenotype without D4Z4 contractions on chromosome 4q35 tested by linear gel electrophoresis and Southern blot analysis.Design and patientsThe authors studied 16 patients displaying an FSHD-like phenotype, with normal...

BACKGROUND: Mutations in SCO2 cause cytochrome c oxidase deficiency (COX) and a fatal infantile cardioencephalomyopathy. SCO2 encodes a protein involved in COX copper metabolism; supplementation with copper salts rescues the defect in patients' cells. Bezafibrate (BZF), an approved hypolipidemic agent, ameliorates the COX deficiency in mice...
