nervous system

increased neuronal precursor proliferation ( J:306384 )

• reduced fraction of granule cell precursors exiting the cell cycle in the anterior lobes of the cerebellum

abnormal cerebellum external granule cell layer morphology ( J:306384 )

• no clear separation of the inner and outer external granule cell layer

decreased cerebellar granule cell number ( J:306384 )

• at P6 in the inner granule layer

abnormal cerebellum anterior lobe morphology ( J:306384 )

• reduced length with failure of Purkinje cells to form a monolayer

• however, the posterior lobes are normal

cellular
