OMIA:002282-9615 : Retinal atrophy, progressive, PDE6B-related 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: 2020
Molecular basis: Winkler et al. (2020): "A 6-bp deletion was identified in exon 19 of PDE6B removing two highly conserved amino acids from the enzymatic domain of the PDE6B protein (c.22182223del; p.Phe740_Phe741del). This segregated with the disease status in the small study pedigree."
Clinical features: Winkler et al. (2020): "Fundus images from an affected ~4.5-year-old dog (SWD IIE) showed advanced retinal degeneration typical of PRA, including vascular attenuation and tapetal hyperreflectivity"
Breed:
Spanish Water Dog (Dog) (VBO_0201280).
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.
