Epidermolysis Bullosa Simplex: A Paradigm for Disorders of Tissue Fragility

The document reviewed the genetic and molecular basis of epidermolysis bullosa simplex (EBS), focusing on mutations in keratin genes K5 and K14 that disrupt skin integrity, leading to fragility and blistering. It discussed various EBS phenotypes, the role of specific mutations, and the impact on keratin filament assembly. Mouse models provided insights into disease mechanisms and potential therapies, such as gene therapy and reprogramming keratin biosynthesis. The review highlighted challenges in developing effective treatments due to the dominant nature of keratin mutations and emphasized the need for further research to understand intermediate filament structure and function.
