Col17a1 knockout mice display the blistering pattern associated with the non-Herlitz subtype and show prolonged survival; whereas Lama3 and Lamc2 knockouts recapitulate the Herlitz type of EB, exhibiting severe skin blistering resulting in perinatal lethality (Bubier et al., 2010; Natsuga et al., 2010). Here, LAMA3 is linked to epidermolysis bullosa.
