Glycosamanoglucan belongs to the chondroitin sulfates (old name: mucopolysaccharide).
Chondroitin sulphates are divided into 2 forms:
- Chondroitin sulphate A: Consists of glycosidically linked glucuronic acid and N-acetylgalactosamine
- Chondroitin sulphate B (dermatan sulphate): Consists of the glycosidically linked L-iduronic acid and N-acetylgalactosamine (see below chondroitin sulphate).

In Pfaundler-Hurler disease, an autosomal recessive mutation of the α-iduronidase gene (gene locus: 4p16.3), a lysosomal degradation of dermatan sulfate (= chondroitin sulfate B) and heparan sulfate occurs in skin and internal organs.
The very rare musculo-contractival Ehlers-Danlos syndrome (mcEDS) is characterized by autosomal recessive inheritance. Mutations in the genes CHST14 and DSE are responsible for mcEDS. The CHST14 gene codes for dermatansulfotransferase-1.
