Mendelian trait/disorder: unknown

Considered a defect: yes

History: Richards and Edwards (1986): "Ataxia of the hind limbs in nine calves was associated with degenerative lesions in spinal white matter and neuronal chromatolysis in red nucleus, spinal grey matter and various nuclei of the medulla oblongata and cerebellum. The clinical signs and lesions ... occurred predominantly in calves of the Murray Grey breed." Edwards et al. (1988): "From analysis of pedigrees and the results of the breeding experiment it was concluded that the condition was inherited as an autosomal recessive condition in Murray Grey cattle."

Breed: Murray Grey (Cattle) (VBO_0000312).
