Gene: Leprfa (leptin receptor; fa mutant) Rattus norvegicus
Symbol: Leprfa
Name: leptin receptor; fa mutant
RGD ID: 13432153
Description: A missense mutation (an A to C conversion at nucleotide position 806) was found in the extracellular domain of all the isoforms in Zucker fatty (fa/fa) rats, which resulted in an amino acid change from Gln to Pro at + 269 (the Gln269Pro mutation).
ASSOCIATED WITH albuminuria; decreased survivor rate; hepatic steatosis; ASSOCIATED WITH Hyperphagia; Insulin Resistance; obesity
Type: allele  of Lepr  
Previously known as: Lepr^[fa]; Leprfa
