N normal phenotype
mortality/aging
• incomplete penetrance, likely due to renal failure from SLE-like disease

neoplasm
• correlated with proliferative phenotype seen in B cells

hematopoietic system
• unimmunized mice at 2 months displayed numerous splenic germinal centers, suggestive of active, proliferative state
• increased B cell proliferation via the immunoglobulin receptor in vitro
• increased T cell receptor mediated proliferation, but T cell development normal
• normal T cell-dependent immune responses, as assessed by antibody titers after immunization with TNP-OVA
• evident between 3 and 6 months of age
• concomitant 50% decrease in long-lived recirculating bone marrow B cells
• 50% increase in the number of pre-B cells in the bone marrow compared to controls
• small, 17% decrease in mature naive B cells
• increased numbers of large, well developed germinal centers evident at 6 weeks of age
• ill-defined marginal zone evident at 6 weeks of age

homeostasis/metabolism
• evident in 7 of 24 3 to 5 month old mice
• evident in 7 of 24 3 to 5 month old mice
• incomplete penetrance, evident in several mice, indicative, along with increased creatinine and urea in serum, of renal failure

immune system
• unimmunized mice at 2 months displayed numerous splenic germinal centers, suggestive of active, proliferative state
• increased B cell proliferation via the immunoglobulin receptor in vitro
• increased T cell receptor mediated proliferation, but T cell development normal
• normal T cell-dependent immune responses, as assessed by antibody titers after immunization with TNP-OVA
• evident between 3 and 6 months of age
• concomitant 50% decrease in long-lived recirculating bone marrow B cells
• 50% increase in the number of pre-B cells in the bone marrow compared to controls
• small, 17% decrease in mature naive B cells
• increased numbers of large, well developed germinal centers evident at 6 weeks of age
• ill-defined marginal zone evident at 6 weeks of age
• SLE-like phenotype seen
• deposition of IgG, IgM, and C3 in glomeruli
• autoantibodies reactive with kidney sections of wild-type mice were detected in 5 or 6 week old mutant mice, but not in controls (J:50626)
• increased autoantibody (anti-ANA, anti-ssDNA, anti-dsDNA, anti-histone) concentrations in serum, especially in female mice (J:81805)
• hypercellularity, lobularity, segmental sclerosis, and enlarged glomeruli, caused by immune complex deposits

renal/urinary system
• incomplete penetrance, evident in several mice, indicative, along with increased creatinine and urea in serum, of renal failure
• hypercellularity, lobularity, segmental sclerosis, and enlarged glomeruli, caused by immune complex deposits

cellular
• unimmunized mice at 2 months displayed numerous splenic germinal centers, suggestive of active, proliferative state
• increased B cell proliferation via the immunoglobulin receptor in vitro
• increased T cell receptor mediated proliferation, but T cell development normal
• normal T cell-dependent immune responses, as assessed by antibody titers after immunization with TNP-OVA

growth/size/body
• evident between 3 and 6 months of age
