Enzyme replacement therapy improves reproductive performance in mucopolysaccharidosis type VII mice but does not prevent postnatal losses.

Abstract excerpt

Mice with mucopolysaccharidosis type VII (MPS VII) are devoid of beta-glucuronidase and accumulate glycosaminoglycans in lysosomes resulting in bone dysplasia, learning disabilities, and decreased mobility. MPS VII males do not breed and, while MPS VII females occasionally mate with heterozygous males, they do not maintain their young postnatally. Heterozygous matings produce less than 25% MPS VII offspring, but...
