Disease
A mutation in the RELN gene has been identified in White Swiss Shepherd dogs that causes cerebellar hypoplasia (CH), a condition where the cerebellum does not develop fully. Affected puppies were born clinically normal, but then they failed to gain weight and developed progressive ataxia at around 2 weeks of age. Affected puppies showed difficulties in standing, walking in a straight line and latching onto the teat, even though the suckling reflex is good. Due to worsening of the symptoms, the puppies had to be euthanized at the age of 4 weeks. Post-mortem examination revealed abnormalities in the brains with severe CH with lissencephaly (abnormal structure of cortical surface folds) and moderate internal hydrocephalus with enlarged lateral vertricles and fourth ventricle.
