Abstract
Dystrophic epidermolysis bullosa is caused by mutations in the COL7A1 gene. The disease characterized by clinical heterogeneity. To date, scientific findings allow to evaluate correlations between the severity of clinical manifestations and genetic defects underlying in the development of the disease. A systematic literature search was performed using PubMed and RSCI, and keywords including “dystrophic epidermolysis bullosa”, “collagen VII”, “COL7A1”. The review includes description of clinical findings of dystrophic epidermolysis bullosa. The types and localization of pathogenic mutations of the COL7A1 gene, their influence on the protein synthesis, structure and functioning are characterized. The correlation between severe course of dystrophic epidermolysis bullosa and mutations resulting in premature termination codons generation which associate with the absence of type VII collagen at the dermo-epidermal junction has been described. Nevertheless, genotype-phenotype correlations should be analyzed carefully due to mechanisms which enable to restore protein expression as well as the possibility of the formation of premature termination codons associated with a more severe course of the disease, when replacing nucleotides in case of their influence on splicing.
