Summaries for Junctional Epidermolysis Bullosa

NIH Rare Diseases : 50 junctional epidermolysis bullosa (jeb) is a type of epidermolysis bullosa, a group of genetic conditions that cause the skin to be very fragile and to blister easily.  jeb is separated into two categories: the herlitz type and the non-herlitz type. the herlitz type of jeb is very severe, and individuals with this condition often do not survive infancy. the non-herlitz type includes several subtypes that cause mild to severe blistering of the skin present at birth or shortly thereafter.   jeb is inherited in an autosomal recessive pattern. it is caused by mutations in the lamb3, col17a1, or lamc2, and lama3 genes.there is no cure for jeb. treatment is focused on management of blistering and prevention of secondary infections. last updated: 2/9/2016

MalaCards based summary : Junctional Epidermolysis Bullosa, also known as epidermolysis bullosa, junctional, is related to epidermolysis bullosa, junctional, non-herlitz type and late-onset junctional epidermolysis bullosa. An important gene associated with Junctional Epidermolysis Bullosa is LAMC2 (Laminin Subunit Gamma 2), and among its related pathways/superpathways are ERK Signaling and Integrin Pathway. The drugs Gentamicins and Anti-Bacterial Agents have been mentioned in the context of this disorder. Affiliated tissues include skin, testes and eye, and related phenotypes are craniofacial and digestive/alimentary

Genetics Home Reference : 25 Junctional epidermolysis bullosa (JEB) is one of the major forms of epidermolysis bullosa, a group of genetic conditions that cause the skin to be very fragile and to blister easily. Blisters and skin erosions form in response to minor injury or friction, such as rubbing or scratching. Researchers classify junctional epidermolysis bullosa into two main types: Herlitz JEB and non-Herlitz JEB. Although the types differ in severity, their features overlap significantly, and they can be caused by mutations in the same genes.
