Structure of seven oligosaccharides excreted in the urine of a patient with Sandhoff's disease (GM2 gangliosidosis-variant O). 1977

G Strecker, and M C Herlant-Peers, and B Fournet, and J Montreul

The urine of a patient with Sandhoff's disease (GM2 gangliosidosis-variant O) contains 10--12 N-acetylglucosamine-rich oligosaccharides in high amounts. The structures of seven of these have been determined: beta-GlcNAc(1--2)-alpha-Man-(1--3)-beta-man-(1--4)-GlcNAc; beta-GlcNAc-(1--4)-alpha-Man-(1--3)-beta-Man-(1--4)-GlcNAc; beta-GlcNAc-(1--2)-alpha-Man-(1--6)-beta-Man-(1--4)-GlcNAc; beta-GlcNAc-(1--4)-alpha-Man-(1--6)-beta-Man-(1--4)-GlcNAc; beta-GlcNAc-(1--2)-alpha-Man-(1--3)-[beta-GlcNAc-(1--2)-alpha-Man-(1--6)]beta-Man-(1--4)-GlcNAc; beta-GlcNAc-(1--2)-alpha-Man-(1--3)[beta-GlcNAc-(1--2)-alpha-Man-(1--6)][beta-GlcNAc-(1--4)]beta-Man-(1--4)-GlcNAc; beta-GlcNAc-(1--2)-alpha-Man(1)-(1--3)[beta-GlcNAc-(1--2)-alpha-Man(2)-(1--6)]beta-Man-(1--4)-GlcNAc, with additional beta-GlcNAc, with additional beta-GlcNAc-(1--4) on mannose (1) or (2). An unusual oligosaccharide, with a tri-branched beta-mannose, has been characterized as the major component excreted in urine.

D005733 Gangliosidoses A group of autosomal recessive lysosomal storage disorders marked by the accumulation of GANGLIOSIDES. They are caused by impaired enzymes or defective cofactors required for normal ganglioside degradation in the LYSOSOMES. Gangliosidoses are classified by the specific ganglioside accumulated in the defective degradation pathway.
