摘要
Provision of a method for accurate diagnosis of mucopolysaccharidoses, including determining the level of glycosaminoglycan in a biological sample with high sensitivity and with ease. A diagnostic method of mucopolysaccharidoses including the following steps (1) and (2): (1) a step including (a) filtering a biological sample with an ultrafiltration filter, digesting the sample on the filter with a glycosaminoglycan-specific enzyme, centrifuging the digested sample to obtain a filtrate, or (b) digesting a biological sample with a glycosaminoglycan-specific enzym, filtering the sample with an ultrafiltration filter to obtain a filtrate, applying the filtrate obtained by (a) or (b) to a liquid chromatograph/mass spectrometer, and analyzing glycosaminoglycan-derived disaccharides, and (2) a step of diagnosing a subject as having mucopolysaccharidosis, chemically diagnosing effect of treatment of mucopolysaccharidoses, or determining types of mucopolysaccharidoses, on the basis of quantitative concentration data and disaccharide composition obtained in step (1).
