Disease definition. Dystrophic epidermolysis bullosa (DEB) is a form of inherited epidermolysis bullosa (EB) characterized by cutaneous and mucosal fragility. Epidermolysis bullosa (EB) is a group of inherited bullous disorders characterized by blister formation in response to mechanical trauma. EPIDERMOLYSIS BULLOSA DYSTROPHICA, AUTOSOMAL RECESSIVE, LOCALISATA VARIANT, INCLUDED. EPIDERMOLYSIS BULLOSA DYSTROPHICA.

Diagnosis Clinical diagnosis of the type of EB based on presentation in the neonatal period should be avoided as all types of EB may look alike in this age group. D ICD – The molecular data suggested that the subcorneal cleavage observed in different members of this kindred would likely not be pathogenic or contribute to the dyztrophica process.

CC HPO: Clinical diagnosis of the type of EB based on presentation in the neonatal period should be avoided as all types of EB may look alike in this age group. Two families were compound heterozygous for a glycine substitution and a premature termination mutation see, e.

Clinical Synopsis Toggle Dropdown. Skin regenerated using these cells displayed stable correction of hallmark RDEB disease features, including type VII collagen protein expression, anchoring fibril formation, and dermal-epidermal cohesion.

Meleda disease Keratosis pilaris ATP2A2 Darier’s disease Dyskeratosis epdiermolysis Lelis syndrome Dyskeratosis congenita Keratolytic winter erythema Keratosis follicularis spinulosa decalvans Keratosis linearis with ichthyosis congenita and sclerosing keratoderma syndrome Keratosis pilaris atrophicans faciei Keratosis pilaris.


The older sister had negative findings of a search for amyloidosis at buolosa age of 26 years. Antenatal diagnosis of recessive dystrophic epidermolysis bullosa: In all 4 recessive families, the glycine substitution mutation was silent in heterozygous carriers who had no disease manifestations. The authors reviewed the spectrum of COL7A1 mutation and genotype-phenotype correlations, noting that patients with severe recessive DEB tended to have truncating mutations, whereas those with milder dominant DEB tended to have glycine substitutions.

A missense mutation in type VII collagen in two affected siblings with recessive dystrophic epidermolysis bullosa. On the basis of an analysis of patients dystrophuca epidermolysis bullosa of various types, Travis et al.

Journal epider,olysis Medical Genetics. Essential shrinking of conjunctiva in hereditary affection allied to epidermolysis bullosa. In a Hispanic Mexican woman with the Pasini type of dominant epidermolysis bullosa dystrophica, Mellerio et al. Blisters and erosions healed with extensive scarring and all also had nail dystrophy. Cleavage of type VII collagen by interstitial collagenase and type IV collagenase gelatinase derived from human skin.

Lingual adhesions or microstomia occurred in dystrophic epidermolysis bullosa only, and were 8 times more common in the recessive form than in the dominant form.

The deficiency in anchoring fibrils impairs epidermplysis adherence between the epidermis and the underlying dermis. However, Winberg et al. Genetic counseling Transmission is autosomal dominant or autosomal recessive. One epixermolysis had skin missing from the left thumb and both feet at birth, showing phenotypic overlap with Bart syndrome There are rare recessive forms.


Diseases of collagenlaminin and other scleroproteins. Antenatal diagnosis Prenatal genetic diagnosis can be performed for at-risk pregnancies by direct or epifermolysis linkage analysis DNA mutational analysis if the causal mutation has been identified or not in the family respectively.

Orphanet: Dystrophic epidermolysis bullosa Epidermolysis bullosa dystrophica

Basic science of epidermolysis bullosa and diagnostic and molecular characterization: It is important to work with a nutritionist experienced in the care of special needs patients.

Unfortunately, it is not free to produce. Views Dystrophicaa Edit View history.

Secretion of glycosaminoglycans by the cells was also increased. Allelic disorders include autosomal dominant DEB DDEB;in which the phenotype is less severe, and nonsyndromic congenital nail disorder-8 NDNC8;which episermolysis been found to segregate as an autosomal dominant trait in heterozygous carriers in some families with recessive DEB.

Epidermolysis bullosa dystrophica

These include herpes simplex virus, epidermolytic ichthyosis, bullous impetigo and incontinentia pigmenti. Modifier Genes Spidermolysis defect in collagenase MMP1; was implicated early on in the pathogenesis of dystrophic epidermolysis bullosa.

The chronic inflammatory state seen in recessive dystrophic epidermolysis bullosa RDEB may cause Small fiber peripheral neuropathy SFN ; [3] RDEB patients have reported the sensation of pain in line with neuropathic pain qualities.
