COL7A1 and junctional epidermolysis bullosa: These same genes, under an autosomal recessive inheritance transmission are responsible for various forms of epidermolysis bullosa (EB: Non-Herlitz junctional epidermolysis bullosa (nH-JEB) COL17A1; recessive dystrophic epidermolysis bullosa (RDEB) COL7A1; junctional EB (JEB) LAMA3, LAMB3, LAMC2) (Masunaga, 2006).
