Type VII collagen is a major component of the anchoring fibrils of the dermal-epidermal adhesion on the dermal side at the lamina densa/papillary dermis interface. Dystrophic epidermolysis bullosa (DEB) emerged…
Laryngo-onycho-cutaneous (LOC) syndrome was reclassified as a subtype of junctional epidermolysis bullosa (JEB) based on clinical features similar to JEB and its association, in the majority of patients from the…
The laminins are a secreted family of heterotrimeric molecules essential for basement membrane formation, structure, and function. It is now well established that the α3 subunit of laminins-332, -321, and…
Non-Herlitz junctional epidermolysis bullosa (nH JEB) is characterized by generalized blisters that predominate in sites exposed to friction, trauma, or heat. Whereas infants and children with nH JEB often appear…
Epidermolysis bullosa (EB) with pyloric atresia (PA) is a rare form of EB. This article describes the clinical and pathologic features and molecular genetics of EB-PA, the mutations in the…
Collagen XVII has been identified as having a role in inherited junctional epidermolysis bullosa non-Herlitz (JEB-other, MIM #226650). The role of collagen XVII in both autoimmune and genetic blistering disorders…
Junctional epidermolysis bullosa type Herlitz (JEB-H) is the autosomal recessively inherited, more severe variant of “lucidolytic” JEB. Characterized by generalized, extensive mucocutaneous blistering at birth and early lethality, this devastating…
A mutation is an event that produces heritable changes in the DNA. There are many different types of mutations, including point mutations (changes that imply loss, duplication, or alterations of…
The prevalence of epidermolysis bullosa simplex (EBS) is estimated to be approximately 6 to 30 per 1 million live births. The disease is usually caused by missense mutations in KRT5…
The dermal-epidermal basement membrane zone is an important epithelial and stromal interface, consisting of an intricately organized collection of intracellular, transmembrane, and extracellular matrix proteins. The basement membrane zone has…
