Clinical case of acral hemorrhagic Darier's disease is not caused by mutations in Exon 15 of the ATP2A2 Gene

Dyskeratosis follicularis (Darier's Disease, DD, MIM#124200) is a genetic skin disorder characterized by the loss of adhesion between epidermal cells (acantholysis) and pathogenetic changes of keratinization with variant forms of cutaneous phenotype. Recently it has been shown that DD cause mutations in the ATP2A2 gene , at 12q24.1. The gene (GenBank accession nos M23115 and M23114) encodes the sacro/endoplasmic reticulum calcium-pumping ATPase (SECRA2), which is highly expressed in keratinocytes. We report on a severe case of the acral mehorrhagic type of DD with an unusual manifestation involving Staphylococcal sepsis. The patient was treated systemically with infusions, oral antibiotics, and retinoids. Antiseptics, keratolytic ointments and creams were given topically to promote epithelization. His condition improved dramatically after 14 days of treatment. All erosions of the trunk, extremities, neck, and head had epithelized. Mutations in exon of the ATP2A2 gene are reported to be the most consistent mutations accosiated with the acral hemorrhagic type of DD (Ruiz-Perez, et al. Hum Molec Genet 1999 ; 8:1621-1630 ; Sakunthabai, et al. Nat Genet 1999 ; 21:271-277). In order to establish genetic background of our patient's clinical phenotype we investigated exon of the ATP2A2 gene. By direct sequencing of the PCR amplified exon 15 of the ATP2A2 gene we did not detect any mutation in our patient's DNA (skin biopsy and blood), nor did we detect mutations in 4 members of his family. Our results show that mutations in exon 15 of the ATP2A2 gene are not a necessary prerequisite for acral hemorrhagic type of DD. Our finfing support the variability of clinical manifestations of DD and a lack of genotype/phenotype consistency.
