I-Cell Disease with GNPTAB Gene Mutation
I-cell disease is a rare inherited metabolic disorder resulting from a defective phosphotransferase, characterized by coarse facial features, skeletal abnormalities and mental retardation. As clinical features of this condition mimic that of Hurler disease mutation studies help in the diagnosis. We present a case of I-cell disease in a neonate with GNPTAB gene mutation.
متن کاملThe p.M292T NDUFS2 mutation causes complex I-deficient Leigh syndrome in multiple families
Isolated complex I deficiency is the most frequently observed oxidative phosphorylation defect in children with mitochondrial disease, leading to a diverse range of clinical presentations, including Leigh syndrome. For most patients the genetic cause of the biochemical defect remains unknown due to incomplete understanding of the complex I assembly process. Nonetheless, a plethora of pathogenic...
متن کاملLeigh syndrome associated with a mutation in the NDUFS7 (PSST) nuclear encoded subunit of complex I.
Leigh syndrome is the phenotypical expression of a genetically heterogeneous cluster of disorders, with pyruvate dehydrogenase complex deficiency and respiratory chain disorders as the main biochemical causes. We report the first missense mutation within the nuclear encoded complex I subunit, NDUFS7, in 2 siblings with neuropathologically proven complex I-deficient Leigh syndrome.
متن کاملLeigh syndrome associated with mitochondrial complex I deficiency due to a novel mutation in the NDUFS1 gene.
BACKGROUND Mutations in the nuclear-encoded subunits of complex I of the mitochondrial respiratory chain are a recognized cause of Leigh syndrome (LS). Recently, 6 mutations in the NDUFS1 gene were identified in 3 families. OBJECTIVE To describe a Spanish family with LS, complex I deficiency in muscle, and a novel mutation in the NDUFS1 gene. DESIGN Using molecular genetic approaches, we id...
متن کاملMutant NDUFS3 subunit of mitochondrial complex I causes Leigh syndrome.
Respiratory chain complex I deficiency represents a genetically heterogeneous group of diseases resulting from mutations in mitochondrial or nuclear genes. Mutations have been reported in 13 of the 14 subunits encoding the core of complex I (seven mitochondrial and six nuclear genes) and these result in Leigh or Leigh-like syndromes or cardiomyopathy. In this study, a combination of denaturing ...
