The LAMA3 gene is the responsible gene of Herlitz type junctional epidermolysis bullosa (OMIM #226700), generalized atrophic benign epidermolysis bullosa (OMIM #226650), and laryngo-onycho-cutaneous syndrome (OMIM #245660) (Kivirikko et al., 1995; McGrath et al., 1995; Vidal et al., 1995; Nakano et al., 2002; McLean et al., 2003).
