Gene Affected endothelin receptor type B: Ednrb
Origin This strain derived from AR (aganglionosis) rat found by Dr. Ikadai in 1973. This congenic strain was established by backcrossing (over 10 generations) of AR rat to F344/Nslc.
Strain characteristics Homozygous rats shows auditory disorder (congenital deafness). 40% of homozygous rats dies of megacolon and this mortality is lower than that of AGH rats (100%). Heterozygous (sl/+) rats don't show any phenotypes.
Breeding Conditions maintained in heterozygous condition: A part of homozygous rats dies of megacolon.
Genotyping Forward Primer: CCTCCTGGACTAGAGGTTCC, Reverse Primer: ACGACTTAGAAAGCTACACT Product size wild-type:511 bp, mutant:210 bp
