OMIA 001575-9615 : Rod-cone dysplasia 4 in Canis lupus familiaris
Downs et al. (2014) reported the same likely causal variant in Standard Poodles and Tibetan Terriers.
Svensson et al. (2016) reported the same likely causal variant in most (but not all) cases in the Polski Owczarek Nizinny breed.
Karlskov-Mortensen et al. (2018) reported the same likely causal variant in the Old Danish Pointing Dog, Miniature Poodles and the Polski Owczarek Podhalanski breed, noting that (given the widespread occurrence in many breeds) the variant must have come into existence prior to the creation of modern dog breeds.Genetic testing: A DNA test for this disorder is provided by the UK Animal Health Trust. Details are available at: http://www.aht.org.uk/genetics_prarcd4.html Breeds: Gordon Setter, Irish Setter. Associated gene:

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.
