N normal phenotype
behavior/neurological
• homozygotes display an enhanced cocaine-induced locomotor response
• strikingly, homozygotes exhibit complete loss of the antidepressant effects of desipramine and reboxetine in the forced swimming test
• homozygotes display reduced analgesia from morphine

hematopoietic system
• homozygotes exhibit impaired platelet aggregation by failing to suppress cAMP formation when adenylyl cyclase is stimulated by PGI2

homeostasis/metabolism
• homozygotes exhibit impaired platelet aggregation by failing to suppress cAMP formation when adenylyl cyclase is stimulated by PGI2
• homozygotes show increased resistance to the fatal thromboembolic effects of collagen plus epinephrine
