They are currently divided into two groups: Appearance of lesions in patients with junctional epidermolysis bullosa. In EBS, the late onset of muscular dystrophy results from defects in the expression of: Pilot data testing was performed in 21 consecutive patients attending an EB clinic. J Hand Surg Br. The clinical spectrum of dystrophic epidermolysis bullosa. The intraepidermal cleavage observed in EBS is the result of mutations in the K5 and K14 genes, which encode the production of keratin and type I and II intermediate filament proteins, expressed in keratinocytes of the basal layer of the epidermis and epithelial-related complexes.
The severity of skin lesions does not necessarily correlate with the degree of muscular dystrophy. EBS is subdivided as follows: In corneal Meesman dystrophy, mutations have been described in CK 3 and With respect to the treatment of lesions, blister puncturing to prevent dissemination and use of sterile dressings are recommended.
