Cross-species summary: This disorder has been renamed in OMIA on the basis of the review by Miyadera et al. (2012). It is also known as retinal pigment epithelial dystrophy.
Inheritance: Rah et al. (2005) characterised an autosomal recessive form of this disorder in Persian cats, and established a breeding colony.
Mapping: To map this disorder, Alhaddad et al. (2014) genotyped each of 106 animals (comprising 37 affecteds and 69 controls) from a colony of Persian cats segregating the disorder (established by Rah et al., 2005) with the illumina Infinium Feline 63 K iSelect DNA array, yielding 47,907 informative SNPs. Using these data, they then conducted a genome-wide linkage analysis, and three GWAS, namely a transmission disequilibrium test (TDT) on 33 discordant trios, a TDT among sib-pairs on 33 discordant sibs, and a case-control association analysis on all 106 animals. All four analyses highlighted an ~ 1.75 Mb region on chromosome FCA E1. Haplotype analysis reduced this region to ~1.3 Mb. The authors noted that this region contains several potential comparative positional and functional candidate genes.
Molecular basis: Lyons et al. (2016): c.577C>T; a predicted p.Arg193*
Prevalence: As reported by Lyons et al. (2016): "Over 1700 cats from 40 different breeds and populations were genotyped for the AIPL1 variant, defining an allelic frequency in only Persian -related breeds of 1.15 %".

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.
