Strain: OLETF

Symbol: OLETF
Strain: OLETF
Full Name: Otsuka Long-Evans Tokushima fatty
RGD ID: 61014
Citation ID: RRID:RGD_61014
Ontology ID: RS:0000284
Type: inbred
Source: Otsuka Research Institute, Tokushima, Japan
Origin: Developed by Kazuya Kawano, Otsuka Pharmaceutical Co., Tokushima, Japan from Long-Evans outbred stock in 1982. A rat with spontaneous polyurea, polyphagia and polydipsia was found in a colony of outbred Long Evans rats purchased from Charles River in 1982. Selective breeding for diabetes with brother x sister mating was subsequently started at the Tokushima Research Institute, Otsuka Pharmaceutical Co., Japan to develop this strain Otsuka Long-Evans Tokushima fatty (OLETF). A deletion of 6847 bases in length in the Cckar gene of the OLETF was identified compared to the wild type gene of the LETO gene sequence'
Genetic Markers: a,B,C,h
Coat Color: Black hooded
Inbred Generations: F46(Otk, 1996)
Last Known Status: Unknown

Substrains
