OMIA 001609-9615 : Exfoliative cutaneous lupus erythematosus in Canis lupus familiaris

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: no

Species-specific description: Exfoliative cutaneous lupus erythematosus is characterized by scaling and crusting skin lesions that progress over the entire body. There is a marker-based test available.

Inheritance: Wang et al. (2011) confirmed the autosomal recessive inheritance of this disorder in German shorthair pointers.

Mapping: By conducting a GWAS on 13 affected and 21 control German shorthaired pointers, each genotyped with the canine Affymetrix 127 k SNP v2 full set chip (yielding 64,987 informative SNPs for analysis), Wang et al. (2011) mapped this disorder to a 0.5 MB region of chromosome CFA18.

Clinical features: This is an exfoliating skin disease, with significant scaling and crusting that begin on the face, ears and back. Scaling progresses to involve the entire body. Secondary infections are common. Lesions can be scales, crusts, pustules, papules, erythema, and/or alopecia (Wang et al., 2011, Vroom et al., 1995, Mauldin et al., 2010). Most affected dogs present before 10 months of age, but signs can begin as late as 2.75 years. Dogs that live with this condition for several years may develop lupus nephritis. Many dogs show lameness and a hunched stance due to arthralgia. Dogs can also become infertile, with low sperm counts and abnormal estrous cycles (Wang et al., 2011, Mauldin et al., 2010).

Pathology: There is a lymphocytic to cell-poor interface dermatitis with vacuoles in the basement membrane region. Severe orthokeratotic hyperkeratosis is seen in the stratum corneum. IgG deposition occurs at the dermoepidermal junction, sometimes with concurrent IgM, IgA, or C3 deposition. Sebaceous glands can be normal, small, or absent. Reactive lymphoid hyperplasia is present in peripheral lymph nodes (Wang et al., 2011). Although these histologic changes can resemble those of systemic lupus erythematosus, discoid lupus erythematosus, and erythema multiforme, cutaneous lupus erythematosus generally begins at a much earlier age (Wang et al., 2011). This disease is more generalized than discoid lupus erythematosus and unlike erythema multiforme, apoptosis in the lower epidermis is absent (Vroom et al., 1995).

Prevalence: This is a rare disease among German shorthaired pointers (Vroom et al., 1995).

Control: Relatives of affected dogs should be tested. Breeding of affected or carrier dogs should be avoided.

Breeds: German Shorthair Pointer, Mixed breed.
