Overview


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.[1] 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. [2][3]  JEB is inherited in an autosomal recessive pattern. It is caused by mutations in the LAMB3, COL17A1, or LAMC2, and LAMA3 genes.[1]
