Liquid-chromatographic detection of aspartylglycosaminuria.
We describe a specific, simple liquid-chromatographic method for detecting the lysosomal storage disease aspartylglycosaminuria. The method is based on identification and quantification of the major storage compound 2-acetamido-1-L-beta-aspartamido-1, 2-dideoxy-beta-D-glucose in the urine of affected individuals. Sample preparation and chromatographic analysis requires 30 min. Within-day variation of the method was less than 4.4%, between-day variation less than 11.7% (n = 10 each).
