Glucosamine-6-sulphatase (G6S), a lysosomal enzyme found in all cells, is involved in the catabolism of heparin, heparan sulphate, and keratan sulphate. Deficiency of G6S results in the accumulation of undegraded substrate and the lysosomal storage disorder mucopolysaccharidosis type IIID (Sanfilippo D syndrome). Regional mapping by in situ hybridization of a 3H-labelled human G6S cDNA probe to human metaphase chromosomes indicated that the G6S gene is localized to chromosome 12 at q14. The localization of the G6S gene to chromosome 12 was confirmed using the G6S cDNA clone in Southern blot hybridization analysis of DNA from human x mouse hybrid cell lines.
