Molecular basis: Linek et al. (2020): "Whole genome sequencing of the affected [Irish Terrier] dog was performed, and the [comparative] functional candidate genes for Darier disease (ATP2A2) and Hailey-Hailey disease (ATP2C1) were investigated. The analysis revealed a heterozygous SINE insertion into the ATP2A2 gene, at the end of intron 14, close to the boundary of exon 15. Analysis of the ATP2A2 mRNA from skin of the affected dog demonstrated a splicing defect and marked allelic imbalance, suggesting nonsense-mediated decay of the resulting aberrant transcripts." Kiener et al. (2023) investigated a 9 year old Shih Tzu with characteristic clinical and histopathologic findings of Darier disease: "Whole genome sequencing of the affected dog identified a heterozygous missense variant, p.N809H, affecting an evolutionarily conserved amino acid residue of the ATP2A2 protein."

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

Clinical features: Sueki et al. (1997) reported skin lesions on the ventral chest of a single 7 month old English Setter and on the head and knee of two of his crossbred offspring: "skin lesions were characterized by hairless, hypertrophic plaques ... The surface of the lesion was rough, with occasional serous crusting and peripheral scaling .... Pruritus was minimal. The lesions enlarged slowly, and no additional lesion developed." Linek et al. (2020) reported a "4-month-old female Irish Terrier ... with a well demarcated ulcerative and crusting lesion in the right ear canal. ... The lesion was successfully treated .... Over the course of three years, the dog additionally developed three dermal nodules of up to 4 cm in diameter that were excised and healed without complications."

Pathology: Sueki et al. (1997): "Histopathologically, these lesions [in the English Setter] showed epidermal hyperplasia with individual enlargement of keratinocytes, extensive acantholysis and minimal dyskeratosis. Ultrastructural analysis revealed that attachment plaques of desmosomes were still intact while some tonofilaments were detached from them in early lesions; there were well-developed microvilli at dissociated cell surfaces." Linek et al. (2020): "clinical, histological, immunohistological, and ultrastructural findings in a male English Setter and two of its female offspring were initially reported as Hailey-Hailey disease [Shanley et al., 1993; Sueki et al., 1997]. A subsequent study found depletion of the ATP2A2-gated stores in cultured keratinocytes from one of these dogs and suggested that these dogs had Darier disease and not Hailey-Hailey disease as previously reported [Müller et al., 2006]." Pathohistology of the Irish Terrier "revealed multiple infundibular cysts extending from the upper dermis to the subcutis. The cysts were lined by squamous epithelium, which presented with abundant acantholysis of suprabasal keratinocytes. Infundibular cysts represent a novel finding not previously reported in Darier patients." (Linek et al., 2020)

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.
