Adenosine deaminases acting on RNA (ADARs) catalyze the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) and thereby potentially alter the information content and structure of cellular RNAs. Notably, although the overwhelming majority of such editing events occur in transcripts derived from Alu repeat elements, the biological(More)
Methylmalonic acidaemia (MMA) is a genetic disorder caused by defects in methylmalonyl-CoA mutase or in any of the different proteins involved in the synthesis of adenosylcobalamin. The aim of this work was to examine the biochemical and clinical phenotype of 32 MMA patients according to their genotype, and to study the mutant mRNA stability by real-time(More)
The mitochondrial DNA m.13513G>A mutation in the ND5 subunit gene is a frequent cause of Leigh syndrome. Patients harboring this mutation typically present with ptosis and cardiac conduction abnormalities, particularly Wolff-Parkinson-White syndrome, and have a late clinical onset, which contrasts with the typical infantile form. The authors describe a(More)
Cofactor disorders of mitochondrial energy metabolism are a heterogeneous group of diseases with a wide variety of clinical symptoms, particular metabolic profiles and variable enzymatic defects. Mutations in NFU1 were recently identified in patients with fatal encephalopathy displaying a biochemical phenotype consistent with defects in lipoic(More)
an L-leucine-sensitive hypoglycaemia. The existence of two siblings in the family reported, and two di†erent reports from di†erent parts of the world, suggest that this is a distinct and inherited entity. All reported patients were boys, but no evidence for a partial ornithine carbamoyltransferase deÐciency could be found, either in our patient or in the(More)
Rett syndrome (RTT) is an early-onset neurodevelopmental disorder that almost exclusively affects girls and is totally disabling. Three genes have been identified that cause RTT: MECP2, CDKL5 and FOXG1. However, the etiology of some of RTT patients still remains unknown. Recently, next generation sequencing (NGS) has promoted genetic diagnoses because of(More)
The 5703G>A mutation in the tRNA gene of mitochondrial DNA seems to show a tissue-specific phenotype: early age of clinical presentation, progressive external ophthalmoplegia, fatigability and ‘extremely thin appearance’. We report a second patient with the same mutation and phenotype.
