Electron ionization mass spectra of reduced and permethylated urinary oligosaccharides from patients with mannosidosis. 1984

I Jardine, and F Matsuura, and C C Sweeley

The electron ionization mass spectra of reduced and permethylated isomeric mixtures of the major urinary tri- to deca-oligosaccharides of patients with mannosidosis are reported. Many of the oligosaccharide isomers can be differentiated in the mixtures on the basis of their distinct fragmentation patterns.

UI	MeSH Term	Description	Entries
D008363	alpha-Mannosidosis	An inborn error of metabolism marked by a defect in the lysosomal isoform of ALPHA-MANNOSIDASE activity that results in lysosomal accumulation of mannose-rich intermediate metabolites. Virtually all patients have psychomotor retardation, facial coarsening, and some degree of dysostosis multiplex. It is thought to be an autosomal recessive disorder.
