Cross-species summary: CLN10
Species-specific description: The neuronal ceroid lipofuscinoses (NCLs) are a group of lysosomal storage diseases characterized by intraneuronal accumulation of fluorescent granules and early neuronal death. Onset is usually before 2 years of age, with death by 7 years of age. Unlike other forms of NCL, dogs with NCL10 do not show signs of cerebral dysfunction or blindness. A genetic test is available.
Molecular basis: The causative variant is a c.597G>A transition in exon 5 of the CTSD gene leading to p.M199I in the encoded cathepsin D (Awano et al., 2006). Cathepsin D-specific activity in affected dogs is approximately 36% of normal.
Clinical features: Onset of signs is usually before 2 years of age and includes hypermetria, dysmetria, paraparesis, ataxia, and progressive psychomotor degeneration. Signs progress slowly, with death by 7 years of age (Awano et al., 2006).Unlike many other NCLs, American bulldogs with NCL10 do not show signs of cerebral dysfunction or blindness (Evans et al, 2005).
Cytoplasmic autofluorescent storage material is present in neurons of the cerebrum, cerebellum, and retina. The most concentrated areas of neuronal cytoplasmic inclusion material is in the gracilic, medial, and lateral cuneate nuclei. Axonal spheroids indicative of neuroaxonal dystrophy are present in the thalamus, caudal medulla, and spinal cord grey matter. Muscle and nerve biopsies have changes consistent with mild denervation (Evans et al., 2005). In the retina, inclusions appear in photoreceptor cells, mostly in cones, in the outer limiting membrane next to the outermost layer of photoreceptor nuclei (Awano et al., 2006).
Prevalence: Allelic frequency was 28% in the American bulldog population studied to identify the causative mutation (Awano et al., 2006).
Control: Relatives of affected dogs should be tested. Avoid breeding affected or carrier dogs.
Genetic testing: A genetic test is available.
Breed: American Bulldog.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
