OMIA:002116-9685 : Coat colour, albinism, oculocutaneous, HPS5-related in Felis catus (domestic cat)

In other species: three-spined stickleback

Categories: Pigmentation phene

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 614074 (trait) , 607521 (gene)

Links to MONDO diseases: No links.

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2020

Species-specific name: Pink-eye

Inheritance: Mériot et al. (2020): "Genealogical data indicated an autosomal recessive inheritance pattern."

Mapping: Mériot et al. (2020): "A single candidate region was identified by genome-wide association study and SNP-based homozygosity mapping. Within that region, we further identified HPS5 (HPS5 Biogenesis Of Lysosomal Organelles Complex 2 Subunit 2) as a strong candidate gene, since HPS5 variants have been identified in humans and animals with Hermansky-Pudlak syndrome 5 or oculocutaneous albinism."

Molecular basis: Mériot et al. (2020): "A homozygous c.2571-1G>A acceptor splice-site variant located in intron 16 of HPS5 was identified in pink-eye cats. Segregation of the variant was 100% consistent with the inheritance pattern. Genotyping of 170 cats from 19 breeds failed to identify a single carrier in non-Donskoy cats. The c.2571-1G>A variant leads to HPS5 exon-16 splicing that is predicted to produce a 52 amino acids in-frame deletion in the protein."

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Clinical features: Mériot et al. (2020): "In the feline Donskoy breed, a phenotype that breeders call "pink-eye," with associated light-brown skin, yellow irises and red-eye effect, has been described."

Breed: Donskoy (Cat) (VBO_0100086).

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.
