strain_characteristics AR rats are characterized by megacolon and white coat color with a small pigmented spot on the head. AR shows a long constricted segment of the intestine, which extended from the distal ileum to the rectum. Histologically, myenteric and submucosal plexus are absent. AR is considered to be an animal model of Hirshsprung???s disease. AR dies of an intestinal obstruction from 1 to 5 weeks of age. The autosomal recessive spotting lethal, sl, was revealed to be caused by a 301-bp interstitial deletion of Endothelin B receptor (Ednrb) 1302502
strain_reproduction Homozygous sl rats die within 1-5 weeks of age. The sl mutation is maintained in heterozygous condition (closed colony). 1302502
