Cross-species summary: One of several variants of neuronal ceroid lipofuscinosis (NCL) or Batten disease: CLN8; NCL8

History: This disorder was first reported by Koppang (1970), who established a colony of English Setters in which the disorder segregated.

Mapping: Lingaas et al. (1998) conducted a genome scan with a panel of 103 microsatellites in a pedigree of "133 animals in three families with a total of 117 offspring". Subsequent genotyping of additional animals with a targetted set of markers from the genome scan enabled Lingaas et al. (1998) to report that "Linkage analysis showed three genetic markers to be linked to the disease locus with the closest marker at a distance of about 3 CM. Two other loci were linked with these markers making a linkage group of five genetic markers. The linkage group spanned a distance of 54 CM." At this time, this linkage group had not been allocated to a particular canine chromosome. By 2005, it was known that this linkage group corresponds to a region of chromosome CFA37 (Katz et al., 2005).

Molecular basis: In one of the early uses of the initial canine genome assembly, Katz et al. (2005) conducted megablast searches of the canine genome with all eight then-known human genes for ceroid lipofuscinosos. One of these (CLN8) was shown to be located on CFA37, near to the mapped location of this disorder (see Mapping section above). Sequencing of the canine CLN8 gene in affected English Setters revealed the causative mutation to be "a T-to-C transition in the CLN8 gene that predicts a p.L164P missense mutation". Whole-genome sequencing of an affected "mixed breed dog with Australian Shepherd and Blue Heeler ancestry" enabled Guo et al. (2014) to identify a nonsense mutation in the CLN8 gene of this dog, namely c.585G>A; p.Trp195*. Genotyping of archival samples enabled these authors to confirm the causality of this mutation. Hirz et al. (2017) reported "a homozygous deletion encompassing the entire CLN8 gene as the most likely causative mutation for the NCL form observed in both cases" "of NCL in Alpenländische Dachsbracke dogs from different litters of the same sire with a different dam". Lingaas et al. (2018) reported a likely causal variant in the Saluki breed, namely a "single bp insertion (c.349dupT) in exon 2, introducing an immediate stop codon (p.Glu117*)" Guo et al. (2019) reported that an affected German Shorthaired Pointer was homozygous for the same nonsense variant as described by Guo et al. (2014).

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Clinical features: Koppang (1992) and Guo et al. (2014) describe the disease in English Setter and Australian Shepherd dogs: From birth to 12-14 months of age, the dog presents as healthy. At 14-18 months, visual impairment and behavioural changes indicative of neurological degeneration, such as decreased responsiveness to voice commands and compulsive circling, develop. These symptoms worsen, leading to blindness, ataxia and eventual loss of motor function in the limbs. Seizures develop at 17-24 months, becoming more frequent and severe until death or euthanasia of the animal which usually occurs before the age of 27 months.

Pathology: Koppang (1992) and Guo et al. (2014) describe the disease in English Setter and Australian Shepherd dogs: Gross pathology as well as MRI examination of the brain identifies diffuse brain atrophy and ventriculomegaly, which progresses alongside clinical signs. Histopathology identifies the accumulation of autofluorescent lysosomal storage material in neural tissue, which is pathognomonic for NCL.

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

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.
