Abstract

Junctional epidermolysis bullosa (JEB) is a heritable blistering skin disease characterized by separation within the lamina lucida. It is caused by mutations in the LAMA3, LAMB3 and LAMC2 genes encoding the α3-, β3- and γ2-chains, respectively, of laminin-332. JEB Herlitz type (JEB-H) is a lethal blistering disease with severe cutaneous and extracutaneous involvements caused by null mutations in the gene encoding laminin-332. Here, we report a proband with JEB-H who is a compound heterozygote for two novel mutations in LAMC2; a missense mutation (c.79G>A) and an insertion mutation (382insT) leading to a premature termination codon.
