N normal phenotype
growth/size/body
decreased body size ( J:114689 )

nervous system
abnormal astrocyte morphology ( J:114689 )
• develop Rosenthal fibers, especially within the hippocampus, olfactory bulb, corpus callosum, and rostral extension, as well as in subpial, perivascular and periventricular regions
• exhibit fewer Rosenthal fibers than seen in heterozygous Gfaptm2Hgmn mutants
