Categories: Vision / eye phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 611755 (trait) , 610189 (trait) , 610142 (gene)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2007

Species-specific name: Late-onset photoreceptor degeneration

Species-specific symbol: rdAc

Molecular basis: Menotti-Raymond et al. (2007) reported a causal mutation: "A single-nucleotide polymorphism was characterized in intron 50 of CEP290 (IVS50 + 9T>G) that creates a strong canonical splice donor site, resulting in a 4-bp insertion and frameshift in the mRNA transcript, with subsequent introduction of a stop codon and premature truncation of the protein."

Clinical features: Minella et al. (2022) reported that "The comparably milder phenotype of CEP290 mutant cats [compared with human patients with CEP290 mutations] is likely due to the retained production of some full-length CEP290 protein with possible functional contributions from presence of truncated protein [in cats homozygous for the splicing variant listed below (OMIA variant 384)]."

Prevalence: Narfström et al. (2009): "A population genetic survey revealed that the rdAc allele is in moderate abundance in the Abyssinian breed in Europe and Australia. Surprisingly, homozygosity for the mutant allele was observed in a Siamese cat with ophthalmoscopic findings similar to those originally described for affected rdAc individuals." Menotti-Raymond et al. (2010) surveyed "41 cat breeds (846 individuals) to assess the incidence, frequency and clinical consequence of rdAc. The rdAc allele [OMIA variant 384] displayed widespread distribution, observed in 16/43 (37%) breeds, exhibiting a high allele frequency (∼33%) in North American and European Siamese populations." The cat sequenced to generate the Felis_catus_9.0 reference genome is homozygous for this variant.

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.

The cat sequenced to generate the Felis_catus_9.0 reference genome is homozygous for the likely causal variant. The genomic and cDNA coordinates had therefore been previously listed in this table as g.112522818TC>A and c.7584+9G>T. The information has been updated based on feedback from 潘旭 to reflect that the likely causal variant is c.7584+9G and that the normal allele is c.7584+9T[6/4/2023]. 2007 17507457 The genomic location on Felis_catus_9.0 and transcript information is based on Rodney et al. 2021 (PMID: 33785770). Variant was initially identified in the Abyssinian and Somali breeds but identified to be present in several other breeds (Menotti-Raymond et al., 2020; Pubmed:19747862; PMID:35709088)
