Claims
Breed: Australian Cattle Dog (Dog)Disorder:Mode of inheritance: Autosomal recessiveSummary: The neuronal ceroid lipofuscinoses (NCLs) are a group of lysosomal storage diseases characterized by intraneuronal accumulation of fluorescent granules and early neuronal death. Affected Border collies present at 18-24 months of age. There is a genetic test available.Clin feat: Dogs present at 18-24 months of age with progressive behavioral changes, hyperactivity, dementia, aggression, loss of coordination, ataxia, delayed postural responses, blindness, and slow pupillary light responses (Taylor et al., 1988, Melville et al., 2005). Blind affected dogs have normal retinal structure on fundic and light microscopic examination, but have severe ultrastructural lesions (Taylor et al., 1988). Changes observed by MRI include slightly dilated cerebral sulci and cerebellar fissures, and left ventricular enlargement (Koie et al., 2004).Defect: yesPathology: There is widespread accumulation of autofluorescent storage granules in the cerebrum, cerebellum, and spinal cord. In the cerebellum there is Purkinje cell depletion, and those remaining contain eosinophilic, autofluorescent granules. Storage also occurs in the ganglion cells of the retina, peribronchial phagocytes, Kupffer cells, macrophages in the spleen, renal tubular epithelium, thyroid epithelial cells, enteric ganglia and submucosal plexus cells (Taylor et al., 1988).Prevalence: The frequency of the c.619Cgt;T allele is estimated at 3.5% in the Border collie population of Australia (Melville et al., 2005). Mizukami et al. (2016) reported the frequency of the c.619Cgt;T allele as 0.035 in 500 Border collies in Japan. Villani et al. (2019) reported the c.619Cgt;T variant to be homozygous in an affected mixed-breed dog of unknown parentage. They also reported a 87kb haplotype including the variant that is shared by this affected dog and the breeds in which this variant has been previously reported. Villani et al. (2019) concluded that the NCL in all of these dogs stems from the same founding mutation event that may have predated the establishment of the modern dog breeds. If so, the CLN5 nonsence allele is probably segregating in other, as yet unidentified, breeds. Thus, dogs exhibiting similar NCL-like signs should be screened for this CLN5 nonsense allele regardless of breed.Control: Relatives of affected dogs should be tested. Avoid breeding affected dogs. If a carrier dog is bred with a dog that is DNA tested to not have the disease causing mutation, then all offspring need to be DNA tested to reduce the risk of future carrier by carrier matings.Gen test: A test is available.

- OMIA molecular-genetics note: Sequencing of the strong comparative positional candidate gene CLN5 (see Mapping section above) revealed to Melville et al. (2005) that the causative mutation in Border Collies is "a nonsense mutation (Q206X) within exon 4" which "should result in a protein product of a size similar to that of some mutations identified in human CLN5 and therefore the Border collie may make a good model for human N…
