OMIA:001675-61379 : Retinal atrophy - Cone-rod dystrophy 2 in Felis nigripes (black-footed cat)

In other species: dog

Categories: Vision / eye phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 609237 (gene) , 609254 (trait)

Single-gene trait/disorder: yes

Mode of inheritance: Autosomal recessive

Disease-related: yes

Key variant known: yes

Year key variant first reported: 2017

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

Molecular basis: Oh et al (2017); '2 base pair (bp) deletion in exon 13 (c.1282delCT) . . . p.L428*'

Clinical features: Oh et al. (2017); 'The diagnosis of early-onset progressive retinal atrophy (PRA) was supported by reduced direct and consensual pupillary light reflexes, phenotypic presence of retinal degeneration, and a non-recordable electroretinogram with negligible amplitudes in both eyes.'

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.
