Mutations in the gamma 2 chain gene (LAMC2) of kalinin/laminin 5 in the junctional forms of epidermolysis bullosa.

Junctional epidermolysis bullosa (JEB) is an autosomal recessive disorder characterized by blister formation within the dermal-epidermal basement membrane. Genes for the lamina lucida protein, kalinin/laminin 5, have been proposed as candidates for some forms of JEB, based on immunofluorescence analysis recognizing kalinin epitopes. We studied the cDNA of laminin gamma 2 chain for mutations in JEB using heteroduplex analysis. One patient showed a homozygous splice site mutation while another was heterozygous for a deletion-insertion, resulting in a premature termination codon in one allele. Our data implicate mutations in the laminin gamma 2 chain gene (LAMC2) in some forms of JEB.[1]
