Mice homozygous for a null allele fail to implant and develop past the 2-cell stage. Heterozygous null females are viable, healthy and fertile but show increased ovary weight, a greater number of empty follicles, a prolonged estrous phase, and reduced nocturnal and stress-induced serum ACTH levels.
