Gene Affected
Origin Rats showing amelogenesis imperfecta were found in the colony of SHR-SP rats at Daiichi Seiyaku, Co., Ltd. in 1985 (Ishibashi, 1990). The SHR-SP was transferred from Kinki University Dr. Okamoto in 1981. Transferred to Tokushima University in 2003. Other name is SHRSP-ami/ami (Aug 30, 2010)
Strain characteristics AMI rats exhibit amelogenesis imperfecta due to underdevelopment of enamel-forming ameloblasts and white incisor. This phenotype is caused by an autosomal recessive gene (ami). (Ishibashi, 1990) (Aug 30, 2010)
Breeding Conditions Maintain homozygous condition by crossing AMI rats. By 20 weeks of age, breeding should be started. (Aug 30, 2010)
