mortality/aging
• mice die of dehydration within 24 hours of birth

nervous system
• at P1, the cerebral cortex lacks pial vasculature unlike in wild-type mice

• mice exhibit defects in blood vessel density compared with wild-type mice
• at P1, mice exhibit a decrease in the number of branch points of blood vessels in the cortex and forebrain while the distance between branch points is increased compared with wild-type mice
• at P1, the cerebral cortex is decreased in size compared to in wild-type mice
• at P1, the cerebral cortex lacks pial vasculature and exhibits cortical degeneration unlike in wild-type mice
• mice exhibit altered cortical neuronal organization compared with wild-type mice
• at E13.5, mice exhibit neuron degeneration in the forebrain unlike wild-type mice
