Species-specific description: Although evidence was initially incomplete, this disorder in cats was expected to be due to variants in the gene for the enzyme procollagen I amino proteinase, which is the enzyme responsible for removing "surplus" amino acids from the N-terminal end of procollagen-I molecules. Simon et al. (2023) confirmed that the disease in European domestic shorthair cats is due to ADAMTS2 loss-of-function variants.

Molecular basis: Simon et al. (2023): "The complete genome of an affected [European domestic shorthair] kitten was sequenced. A one base pair duplication, c.698dup, leading to a frameshift in the candidate gene ADAMTS2 was identified, p.(Ser235fs*3). The variant is located in a polyC stretch and leads to an expansion from 8 to 9 cytosines in the mutant allele. All four affected cats [sired by the same tomcat, but born by three different mothers] carried the frameshift duplication in a homozygous state. Genotypes at this variant showed perfect co-segregation with the autosomal recessive EDS phenotype in the available family. The mutant allele did not occur in 48 unrelated control cats."

Clinical features: Simon et al. (2023): "The [European domestic shorthair] kittens had easily torn skin resulting in non-healing skin wounds."

Pathology: Simon et al. (2023): "Both clinically and histologically, the skin [of affected European domestic shorthair kittens] showed thin epidermis in addition to inflammatory changes. Changes in collagen fibers were visible in electron micrographs."

Breeds: Domestic Shorthair, Himalayan (Cat) (VBO_0100117).

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.
