albuminuria
(
J:84701
)
• apparent in most at 3 months of age
|
renal/urinary system
• formation of ballooning glomerular capillaries in late gestation
|
albuminuria
(
J:84701
)
• apparent in most at 3 months of age
|
• delayed formation of the renal glomerulus mesangium
|
• embryos exhibit a reduction in the number of mesangial cells in glomeruli at late gestation, leading to the formation of ballooning glomerular capillaries
• the mesangial cell deficiency is temporary and by 1 month of age, most glomeruli are normalized
|
• by 6 months of age, mice show extensive accumulation of extracellular matrix
|
vision/eye
• about 10% display white ocular opacities
|
• 100% penetrance
|
• the retinal vasculature is severely disorganized and retinal vessels are abnormal from the onset of sprouting
• plexus formation is delayed and asymmetric at P2, the vascular plexuses at P5 are highly irregular and display fewer sprouts and sites with increased as well as decreased vascular density
• vascular remodeling occurs but the pattern of remodeled vessels is abnormal, with a shortage of branch points
• retinal plexuses show a significant reduction in the pericyte density and pericytes in the retina are partially detached from the endothelium
|
• invasion of retinal pigment epithelial cells
|
• degeneration of the nuclear layer
|
• degeneration of the photoreceptor layer
|
• fibrosis and traction
|
cardiovascular system
• abnormal capillary morphology in postnatal mice
|
• formation of ballooning glomerular capillaries in late gestation
|
• the retinal vasculature is severely disorganized and retinal vessels are abnormal from the onset of sprouting
• plexus formation is delayed and asymmetric at P2, the vascular plexuses at P5 are highly irregular and display fewer sprouts and sites with increased as well as decreased vascular density
• vascular remodeling occurs but the pattern of remodeled vessels is abnormal, with a shortage of branch points
• retinal plexuses show a significant reduction in the pericyte density and pericytes in the retina are partially detached from the endothelium
|
• at E15.5, the number of pericytes in the forebrain is reduced to about 50% of normal
• pericytes in the brain are partially dissociated from the abluminal endothelial surface and protrude cellular processes away from the vessel
• pericytes in the retina are partially detached from the endothelium
|
• vessel-associated vascular smooth muscle cells are present but abnormally organized in the retina
|
growth/size/body
• slightly growth retarded
|
nervous system
pigmentation
• invasion of retinal pigment epithelial cells
|
reproductive system
muscle
• vessel-associated vascular smooth muscle cells are present but abnormally organized in the retina
|
cellular
