A novel ENU-induced mutation, peewee, causes dwarfism in the mouse.

Abstract excerpt

We identified a novel fertile autosomal recessive mutation called peewee that results in dwarfing, in a region-specific ENU-induced mutagenesis. These mice at litter size were smaller those of other strains. Histological analysis revealed that the major organs appear normal, but abnormalities in cellular proliferation were observed in bone, liver, and testis. Haplotype analysis localized the peewee gene to a...
