hematopoietic system
• heterozygotes display progressively increased red blood cell counts relative to wild-type mice (10.1 0.3 106/mm3 vs 9.7 0.1 106/mm3, respectively)
• heterozygotes display progressively increased hematocrits relative to wild-type mice (51.8 0.9 vs 49.9 1.0, respectively)
• heterozygotes display progressively increased hemoglobin levels relative to wild-type mice (16.2 0.2 g/dl vs 15.6 0.2 g/dl, respectively)

homeostasis/metabolism
• homozygotes exhibit a >200% increase in total daily excretion of cGMP in the urine relative to wild-type mice
• heterozygotes can excrete dilute urine after water loading but become progressively and significantly less able to concentrate urine relative to wild-type mice

cardiovascular system
• heterozygotes exhibit reduced intravascular blood volume; however, no reduction in blood pressure is observed relative to wild-type mice

renal/urinary system
• homozygotes exhibit a >200% increase in total daily excretion of cGMP in the urine relative to wild-type mice
• heterozygotes can excrete dilute urine after water loading but become progressively and significantly less able to concentrate urine relative to wild-type mice
• similar to homozygotes, heterozygotes show a mild progressive increase in total daily urine output relative to wild-type littermates
