Year key variant first reported: 2015

Species-specific name: Cone degeneration - hemeralopia/achromatopsia

Molecular basis: Tanaka et al. (2015): "a missense mutation in exon 7 (c.C1270T/p.R424W) in the German shepherd breed and a 3nt deletion in exon 7 (c.1931_1933delTGG/p.V644del) in Labrador retrievers"

Breeds: German Shepherd Dog (Dog) (VBO_0200577), Labrador Retriever (Dog) (VBO_0200800).
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.
