mortality/aging
• no homozygotes survive beyond 7 weeks of age whereas Inpp5dtm1Dmt/tm1Dmt mice show 50% survival at 6 months

growth/size/body
• exhibit runting at weaning although present in expected numbers
• failure to thrive after weaning
• due to increased erythropoiesis

respiratory system
• alveoli of mice at 4 weeks of age are filled with lipid laden macrophage containing eosinophilic Ym1 crystals
• of mice at 4 weeks of age

hematopoietic system
• very small thymus
• due to increased erythropoiesis
• increased erythropoiesis
• in 4 week old mice
• in 4 week old mice
• significantly reduced circulating lymphocyte cell number at 4 weeks of age relative to Inpp5dtm1Dmt/tm1Dmt mice
• reduction in mature B cells in bone marrow 4 weeks of age
• double positive thymocytes in particular are reduced
• 50 fold reduction in pre-B cells in bone marrow 4 weeks of age
