Key variant known: yes
Year key variant first reported: 2010
Cross-species summary: This disorder has been renamed in OMIA on the basis of the review by Miyadera et al. (2012)
Species-specific name: cmr3
Species-specific description: Canine multifocal retinopathy (cmr) is an ocular disorder characterized by multiple areas of retinal degeneration. The disorder detailed in this entry (cmr3) has essentially the same cinical signs as the other two forms of cmr (namely cmr1 [OMIA001553-9615] and cmr2 [OMIA001554-9615]), but as explained by Zangerl et al. (2010), the nature of the cmr3 mutation suggests a different molecular mechanism.
Mapping: CFA18
Molecular basis: The causative mutations for Cmr3 in the Lapponian herder are a deletion and a G to T substitution in exon 10 of BEST1 (Zangerl et al., 2010).
Clinical features: Signs of cmr include multiple tan-pink subretinal patches in both the tapetal and the non-tapetal fundus along with focal areas of tapetal hyper-reflectivity. The lesions elevate the retina, progressing as the dog ages, to focal areas of retinal degeneration and retinal pigment epithelial hypertrophy and pigmentation (Grahn et al., 1998).
Pathology: In retinal histology there are multiple areas of retinal pigment epithelial vacuolation, hypertrophy, apparent separation from Bruch’s membrane, and multiple serous retinal detachments (Grahn et al., 1998).
Control: Relatives of affected dogs should be tested. Breeding of affected or carrier animals is not recommended. If carriers must be bred, it should be bred only to a tested, homozygous normal dog.
Genetic testing: There are tests available to detect the known causative mutations.
Breeds:
Finnish Lapphund (Dog) (VBO_0200523),
Lapponian Herder (Dog) (VBO_0200814).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).

Variants
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.
