Species-specific description: Kiener et al. (2023) investigated 2 domestic shorthair kittens with sebaceous gland dysplasia. Clinical and histopathological changes were similar but not identical to previously reported cases of sebaceous gland dysplasia in cats (Yager et al. 2012, OMIA:001710-9685 : Sebaceous gland dysplasia in Felis catus) and genetic analysis suggests genetic heterogeneity of this phenotype.
Molecular basis: Kiener et al. (2023) "Whole genome sequencing on both affected kittens and 65 genetically diverse feline genomes was performed. Filtering for variants that were present in both kittens but absent from the control genomes revealed a homozygous missense variant in SOAT1, encoding sterol O-acyltransferase 1. The protein is localized in the endoplasmic reticulum and catalyzes the formation of cholesteryl esters, an essential component of sebum and meibum. ... We further genotyped archived samples from 10 additional cats [including one cat from the Yager et al. (2012) study] with a similar clinical and histopathological phenotype, as well as 716 genetically diverse population controls from the Vetsuisse Biobank, all of which were homozygous wildtype."
Genetic engineering:
Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
Clinical features: Kiener et al. (2023) "investigated two 4-month-old sibling domestic short haired kittens with dry dark debris around the eyes, nose, and ears, dark crusting on the legs and a thin poor hair coat."
Pathology: Kiener et al. (2023) "Skin biopsies revealed abnormal sebaceous gland morphology with lack of normal sebocyte arrangement and differentiation. Hair follicles had a distorted silhouette, interpreted as a change secondary to the observed sebaceous gland dysplasia."
Breed:
Domestic Shorthair.

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.
