N normal phenotype
renal/urinary system
• as early as 4 weeks of age, mice exhibit significantly higher urinary albumin:creatinine ratios relative to wild-type controls
• at 2-6 months of age, albumin:creatinine ratios are significantly higher than those in podocyte-specific knockouts generated on a predominantly C57BL/6 background
• by 4 months of age, the average number of foot processes per unit length of the basement membrane is reduced relative to than in wild-type controls
• as early as 2 months of age, mice exhibit widespread foot process effacement, unlike wild-type controls
• by 4 months of age, podocytes exhibit microvillus transformation, indicating damage
• as early as 2 months of age, mice exhibit significant GBM alterations relative to wild-type controls
• by 4 months of age, a highly variable GBM disorganization with characteristic electronlucent or "moth-eaten" regions is observed, unlike in wild-type controls
• the overall GBM outline appears jagged and uneven
• by 4 months of age, average GBM thickness is increased relative to that in wild-type controls
• at 4 months of age, mice exhibit multiple sclerotic glomeruli, unlike control mice
• at 4 months of age, mice exhibit multiple renal casts, unlike control mice

homeostasis/metabolism
• as early as 4 weeks of age, mice exhibit significantly higher urinary albumin:creatinine ratios relative to wild-type controls
• at 2-6 months of age, albumin:creatinine ratios are significantly higher than those in podocyte-specific knockouts generated on a predominantly C57BL/6 background
