Crhr1tm1Wrst mutation (1 available); any Crhr1 mutation (26 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• compared with homozygous mutant and wild-type mice, heterozygous mutant mice displayed an intermediate reduction in anxiety-related performance under ethanol-withdrawal conditions in the light-dark box, suggesting a gene-dosage effect

homeostasis/metabolism
N
• heterozygous mutant males and females displayed normal basal levels of POMC1 (ACTH)
• heterozygous mutant mice displayed a normal HPA axis response to forced-swim stress: similar to wild-type, heterozygous females and males responded by significantly increasing circulating levels of POMC1 (ACTH)
