Phenotypes Associated with This Genotype

Genotype
MGI:2182596

• Allelic Composition: Cln6^nclf/Cln6^nclf
• Genetic Background: involves: C57BL/6J * C57BL/10J * C3HeB/FeJLe

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

premature death ( J:47292 )

behavior/neurological

paralysis ( J:47292 )

• paresis progresses to paralysis typically by 9 months of age

• paralysis is spastic in nature

hindlimb paresis ( J:47292 )

• develop rear limb paresis by 8 months of age

• paresis is spastic in nature

seizures ( J:47292 )

• terminal seizures have been seen

nervous system

seizures ( J:47292 )

• terminal seizures have been seen

astrocytosis ( J:47292 )

• by 6 months of age increasing numbers of hypertrophic astrocytes are seen in the cerebral cortex, thalamus and brain stem indicative of reactive gliosis

axon degeneration ( J:47292 )

• many profiles of degenerating myelin sheaths and axons are seen in the white matter of the spinal cord

• lesions in the spinal cord are consistent with Wallerian degeneration

• however, no necrotic or apoptotic nuclei are detected in the central nervous system

abnormal myelination ( J:47292 )

• many profiles of degenerating myelin sheaths and axons are seen in the white matter of the spinal cord

• lesions in the spinal cord are consistent with Wallerian degeneration

abnormal neuron physiology ( J:47292 )

• at 11 days of age, accumulation of luxol fast blue staining material is seen in inclusions in neurons in all parts of the brain and spinal cord

• amount of inclusion material increases with age

vision/eye

increased susceptibility to age-related retinal degeneration ( J:47292 )

• begins around 4 months of age

• by 5 - 6 months of age, the outer nuclear layer is reduced to 5-6 cell layers compared to 11 in controls
