nervous system
• in some mice
• some mice exhibit diastematomyelia, splitting of the spinal cord, due to bony septa in lumbar L3 and L4 vertebrae unlike in wild-type mice
• 60% of mice exhibit abnormal brain morphology
• brain gray matter is lost in a gradient in some mice unlike in wild-type mice
• some mice develop secondary hydrocephalus unlike in wild-type mice
• partial agenesis in some mice
• in most mice due to increased cellular proliferation
• some mice exhibit deformations in the hippocampal cortex unlike in wild-type mice
• in most mice, the posterior cortex is smaller than in wild-type mice due to reduced cellular proliferation
• disorganized in some mice
• in pronounced cases, dramatic cerebellar herniation through the foramen magnum is observed with secondary hydrocephalus unlike in wild-type mice
• MRI imaging shows herniation of the cerebellar paraflocculus into the foramen magnum with crowded posterior fosssa in some mice unlike in wild-type mice

behavior/neurological
