Description

These mutant mice exhibit lysosomal storage disease and may serve as a model for Sly disease in humans.

Detailed description

Mice homozygous for the Gusb^mps allele exhibit skeletal dysplasia as well as cognitive, hearing and visual deficits. Lifespan of the homozygotes is approximately six months. Homozygotes lack the lysomal enzyme, beta-glucoronidase, and, as a result, glycosaminoglycans accumulate in tissues throughout the body. Female homozygotes rarely conceive and do not lactate. This strain is a model for the human lysomal storage disease, mucopolysaccharidosis type VII.

Development

The Gusb^mps mutation arose spontaneously on B6.C-H2^bm1/By in 1976 (Birkenmeier et al., 1989). This strain is derived from Stock No. 000256 and cryopreserved as homozygous sperm in 2007.
