OMIA:002238-9685 : Ichthyosis, ABCA12-related in Felis catus (domestic cat)

In other species: pig , taurine cattle

Categories: Integument (skin) phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 601277 (trait) , 242500 (trait) , 607800 (gene)

Links to relevant human diseases in MONDO:

Single-gene trait/disorder: yes

Mode of inheritance: Probably autosomal recessive

Disease-related: yes

Key variant known: yes

Year key variant first reported: 2025

Molecular basis: Blake et al. (2025) reported two random bred littermates with ichthyosis fetalis: "Genetic analysis identified a homozygous one base pair deletion in ABCA12 [XM_019838638.2:c.6926delC], resulting in a frameshift and predicted loss of function of the encoded protein [ABCA12:p.Pro2201fsTer9]. Genotyping of 140 unrelated cats revealed that all were homozygous for the wild-type allele." 

Breed: Domestic Shorthair (Cat) (VBO_0100119).
Breeds in which the phene or likely causal variants have been documented. If a likely causal variant has been documented, see variant-specific breed information in the variant table. (Breed information may be incomplete).

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.
