Species-specific description: Ataxia is characterized by uncoordinated movements and represents a relatively non-specific clinical sign. This entry describes an ataxia form that is caused by a genetic variant in the SEL1L gene. Phenotypically related ataxias in dogs may also be caused by variants in the ATP1B2, CAPN1, GRM1, ITPR1, KCNJ10, RAB24, SNX14, and SPTBN2 genes. Thus locus heterogeneity for this phenotype must be considered.

History: This type of ataxia was first reported by Tonttila and Lindberg (1971).

Mapping: As reported by Kyöstilä et al. (2012), "A genome-wide association study [GWAS] in a cohort of 31 dogs mapped the ataxia gene to a 1.5 Mb locus on canine chromosome 8".

Molecular basis: Kyöstilä et al. (2012) reported the causative mutation as being a "missense mutation, c.1972T>C; p.Ser658Pro, in a highly conserved protein domain" of the SEL1L gene, whose peptide is a "component of the endoplasmic reticulum (ER)–associated protein degradation (ERAD) machinery". Since mutations in this gene have not previously been reported in any species, this discovery provides a new potential candidate gene for human progressive childhood ataxias.

Clinical features: "Neurological examinations on ten affected dogs revealed rapidly progressing generalized cerebellar ataxia, tremors, and failure to thrive. Clinical signs were present by the age of 3 months, and cerebellar shrinkage was detectable through MRI." (Kyöstilä et al. (2012)

Pathology: "Pathological and histological examinations indicated cerebellum-restricted neurodegeneration. Marked loss of Purkinje cells was detected in the cerebellar cortex with secondary changes in other cortical layers." (Kyöstilä et al. (2012)

Control: A simple blood test is now available for detecting carriers of the causative mutation.

Breed: Finnish Hound (Dog) (VBO_0200522).

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.
