Gene Affected |
Tg: thyroglobulin |
Origin |
The WIC-rdw rat, established from a closed colony of Wistar-Imamichi (WIC) rats as a spontaneous mutant exhibiting congenital dwarfism (rdw), is inherited as an autosomal recessive. |
Strain characteristics |
A convincing line of evidence is being developed that the congenital nongoitrous hypothyroidism and dwarfism observed in the WIC-rdw rat may indeed be caused by a primary defect in thyroid hormonogenesis. In support of this hypothesis, several recent reports have shown the presence of elevated molecular chaperone levels in the WIC-rdw thyrocytes, the endoplasmic reticulum of which was markedly dilated, suggesting a defect in intracellular protein transport. It was reported that A missense mutation, G2320R, in the Tg gene is responsible for the rdw mutation in the WIC-rdw rat. |
Breeding Conditions |
Homozygous rdw rats are infertile in both sexes. So, the mutant rats are maintained as a segregating inbred strain. |
