Summaries for Transient Bullous Dermolysis of the Newborn

NIH Rare Diseases : 54 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 79411Disease definitionTransient bullous dermolysis of the newborn is a rare subtype of dystrophic epidermolysis bullosa (DEB, see this term) characterized by generalized blistering at birth that usually regresses within the first 6 to 24 months of life.EpidemiologyPrevalence is unknown. Less than 30 cases have been reported to date.Clinical descriptionThe disease usually manifests at birth. Skin blisters generally affect the whole body. Blisters can also affect the oral cavity. Healing of blisters is associated with mild, mostly atrophic, scarring and milia formation. Disease activity usually ceases within the first 6 to 24 months of life. However, nail dystrophy and some degree of skin fragility can persist in adulthood. Ultrastructurally, the presence in basal keratinocytes of peculiar cytoplasmic inclusions, known as stellate bodies, filled with unsecreted procollagen VII, is typical of the disease.EtiologyTransient bullous dermolysis of the newborn is caused by mutations within the type VII collagen gene (COL7A1). Mutations in this gene lead to reduced amounts or an alteration in function of collagen VII. This impairs its assembly into anchoring fibrils that anchor the basement membrane to the underlying dermis.Genetic counselingThe condition is usually inherited in an autosomal dominant manner, but can also rarely be transmitted as an autosomal recessivetrait.Visit the Orphanet disease page for more resources.

MalaCards based summary : Transient Bullous Dermolysis of the Newborn, also known as tbdn, is related to nail disorder, nonsyndromic congenital, 8 and epidermolysis bullosa dystrophica. An important gene associated with Transient Bullous Dermolysis of the Newborn is COL7A1 (Collagen Type VII Alpha 1 Chain). Affiliated tissues include skin, and related phenotypes are nail dystrophy and hypopigmented skin patches

OMIM : 58 Transient bullous dermolysis of the newborn is a rare form of dystrophic epidermolysis bullosa (DEB) that presents with neonatal skin blistering but usually improves markedly during early life and even remits completely. Skin biopsies reveal abnormal intraepidermal accumulation of type VII collagen, which results in poorly constructed anchoring fibrils and a sublamina densa plane of blister formation (summary by Fassihi et al., 2005). (131705)

UniProtKB/Swiss-Prot : 76 Transient bullous dermolysis of the newborn: TBDN is a neonatal form of dystrophic epidermolysis bullosa characterized by sub-epidermal blisters, reduced or abnormal anchoring fibrils at the dermo-epidermal junction, and electron-dense inclusions in keratinocytes. TBDN heals spontaneously or strongly improves within the first months and years of life.
