Ribose-5-Phosphate Isomerase Deficiency

Ribose 5 Phosphate Isomerase Deficiency


Presentation

  • The present article describes the first patient with a deficiency of ribose-5-phosphate isomerase (RPI) (Enzyme Commission number 5.3.1.6) who presented with leukoencephalopathy and peripheral neuropathy.[ncbi.nlm.nih.gov]
  • Furthermore, we present a transgenic yeast model, which exhibits metabolite- and enzyme-activity changes that correspond to the human syndrome and show that the decrease in RPI activity in patient cells is not fully attributable to the residue exchange[ncbi.nlm.nih.gov]
  • Definition A patient has been described with a deficiency of ribose 5-phosphate isomerase who presented with leukoencephalopathy and peripheral neuropathy.[uniprot.org]
  • However, the focus of the book remains clinical, describing symptoms and signs at presentation, how to come to a diagnosis and methods for treatment. As with the previous edition, the book can be used in two main ways.[books.google.com]
  • The patient presented with progressive leukoencephalopathy and peripheral neuropathy. Systematic metabolic profiling identified elevated levels of arabitol and ribitol in affected brain regions and body fluids.[genome.jp]
