mortality/aging
• small but significant increase in mortality by 18 months

hematopoietic system
• variable red blood cell size
• high levels of reticulocytes in peripheral blood, up to 30%
• severity of reticulocytosis increases with age
• increase as kidney disease develops
• mild to moderate
• increased numbers of erythroblasts in bone marrow
• elevated erythroid precursors
• lymphoid tissues are otherwise normal
• marked splenomegaly at all ages examined
• reduced osmotic fragility
• starting at 10 weeks of age
• starting at 10 weeks of age
• starting at 10 weeks of age

renal/urinary system
• an expanded mesangial matrix often causes obstruction of capillary lumina
• extensive scarring of the kidneys develops
• normal to at least 3 months of age
• low or moderate
• in about 30% of homozygotes
• in about 60% of mice
• in more than 80% of homozygotes at 12 months of age
• elevated Ig and C3 deposition in kidney glomeruli by 6 months
• frequently elevated mononuclear leukocyte infiltrates

liver/biliary system
• mononuclear leukocyte infiltrates are frequently elevated

respiratory system
• mononuclear leukocyte infiltrates are frequently elevated

immune system
N
• B and T cell development and function normal (J:74579)
• increase as kidney disease develops
• elevated erythroid precursors
• lymphoid tissues are otherwise normal
• marked splenomegaly at all ages examined
• circulating immune complexes become elevated
• starting at 10 weeks of age
• starting at 10 weeks of age
• starting at 10 weeks of age
• antinuclear antibody in about 60% of mice having hematuria
• mononuclear leukocyte infiltrates are frequently elevated
• in more than 80% of homozygotes at 12 months of age
• elevated Ig and C3 deposition in kidney glomeruli by 6 months
• frequently elevated mononuclear leukocyte infiltrates
• mononuclear leukocyte infiltrates are frequently elevated

homeostasis/metabolism
• low or moderate
• in about 30% of homozygotes
