OMIA:001669-9615 : Retinal atrophy - Rod-cone dysplasia 1a in Canis lupus familiaris (dog) |
Categories: Vision / eye phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 163500 (trait) , 613801 (trait) , 180072 (gene)
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Disease-related: yes
Key variant known: yes
Year key variant first reported: 2000
Cross-species summary: This disorder has been named in OMIA on the basis of the review by Miyadera et al. (2012)
Species-specific symbol: rcd1a
Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Dekomien et al. (2000) reported the causal mutation in Sloughi dogs as being "an 8-bp insertion after codon 816" of the PDE6B gene.
Breed:
Sloughi (Dog) (VBO_0201242).
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).
Associated gene:

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.
