mortality/aging
• rare survivors die by P30
• nearly all mice die by between P1 and P3

nervous system
• in rare survivors
• neuronal progenitors exit the cell cycle prematurely and differentiate
• neurite outgrowth is impaired compared to in wild-type mice
• between E13 and E19, neuronal progenitor cells in the ventricular zone exhibit a migratory defect that prevents them from entering intermediate layers unlike in wild-type mice
• at E18, radial migration of proliferating cells into the cortex is impaired compared to in wild-type mice
• neuronal progenitors fail to reach the medial pallium unlike in wild-type mice
• interkinetic nuclear migration in the ventricular zone is impaired compared to in wild-type mice
• at E14 and E16, mice exhibit impaired cell proliferation of cells in the ventricular zone compared to in wild-type mice
• large parts of layers II, III, and IV are missing compared with wild-type mice
• however, the upper molecular layer I and the inner multiform layer VI are present
• neurites are shorter than in wild-type cells

• in rare survivors

mortality/aging
• mice exhibit a reduced life span with a median age at death of 9 months

homeostasis/metabolism
• significant increase in serum creatinine levels at 6 months of age, indicating renal dysfunction
• large ascites detected at 9 months of age
• mice develop persistent proteinuria by 3 months of age
• rate of proteinuria increases modestly until 6 months and accelerates more rapidly thereafter
• after induction of kidney podocyte injury by protamine sulfate (PS) perfusion, mutant foot processes exhibit a broadened and flattened morphology that is distinct from that in wild-type controls
• PS-treated mutant podocytes develop unusually long fine processes that project from primary, secondary, and tertiary processes, suggesting pseudovillous transformation
• PS-treated mutant podocytes fail to recover normal morphology following subsequent infusion of heparin sulfate, unlike wild-type controls

renal/urinary system
N
• mice exhibit no evidence of glomerular or interstitial scarring, even at 9 months of age
• mice develop persistent proteinuria by 3 months of age
• rate of proteinuria increases modestly until 6 months and accelerates more rapidly thereafter
• mice exhibit evidence of fine finger-like projections from the podocyte cell bodies and processes at 6 months of age
• foot process spreading is evident by 8 months of age
• following PS perfusion, foot processes exhibit a broadened and flattened morphology that is distinct from that in wild-type controls
• PS-treated podocytes develop unusually long fine processes that project from primary, secondary, and tertiary processes, suggesting pseudovillous transformation
• PS-treated mutant podocytes fail to recover normal morphology following subsequent infusion of heparin sulfate, unlike wild-type controls

integument
• mice exhibit a scruffed appearance at 9 months of age
