Description : Epidermolysis bullosa simplex is a clinically and genetically heterogeneous skin disorder
characterized by blistering of the skin following minor physical trauma as a result
of cytolysis within the basal epidermal cells. Most forms show autosomal dominant
inheritance. The localized form is characterized by localized blistering primarily
on the hands and feet (Pfendner et al., 2005). The other 2 main types of EBS include
the milder generalized Koebner type (131900) and the more severe Dowling-Meara type
(131760). All 3 forms can be caused by mutation in the KRT5 or KRT14 genes (summary
by Fine et al., 2008).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the keratin 5 gene (KRT5, 148040.0003); Caused by mutation in the keratin 14 gene (KRT14, 148066.0005);
