OMIA 001314-9615 : Rod-cone dysplasia 3 in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 613810 (trait) , 180071 (gene)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 1999

Cross-species summary: This disorder has been renamed in OMIA on the basis of the review by Miyadera et al. (2012)

Species-specific symbol: rcd3

History: The first report of this disorder was by Keep (1972).

Mapping: The first step in the investigation of Petersen-Jones et al. (1999) was to show that the canine PDE6A gene co-segregates with the disorder.

Molecular basis: By mapping, cloning and sequencing a very likely comparative candidate gene (based on information concerning closely related genes associated with similar disorders in humans and dogs), Petersen-Jones et al. (1999) showed that the molecular basis of this particular type of progressive retinal atrophy is the deletion of a single base in codon 616 of the gene for the alpha subunit of cyclic guanosine monophosphate (cGMP) phosphodiesterase (PDE6A), which is "predicted to lead to a frame shift resulting in a string of 28 altered codons followed by a premature stop codon".

Breed: Cardigan Welsh Corgi.

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.
