Somatic forward (nonrevertant) mosaicism in recessive dystrophic epidermolysis bullosa.
angiofibromas.4 Successful treatment of nonangiofibroma cutaneous manifestations of TSC has been sparse. To our knowledge, topical rapamycin has not been used successfully to treat the ungual fibromas of TSC. In our case, the use of topical rapamycin was well tolerated and resulted in the resolution of subungual tumors and rapid normalization of the overlying nail distortion. The pathogenesis o...
متن کاملRevertant Mosaicism in Epidermolysis Bullosa Caused by Mitotic Gene Conversion
Mitotic gene conversion acting as reverse mutation has not been previously demonstrated in human. We report here that the revertant mosaicism of a compound heterozygous proband with an autosomal recessive genodermatosis, generalized atrophic benign epidermolysis bullosa, is caused by mitotic gene conversion of one of the two mutated COL17A1 alleles. Specifically, the maternal allele surrounding...
متن کاملThree Brothers with Recessive Dystrophic Epidermolysis Bullosa
Epidermolysis bullosa (EB) is a group of heritable mechano-bullous skin diseases classified into three major categories on the basis of the level of tissue separation within the dermal-epidermal basement membrane zone. In the most severe, dystrophic (scarring) forms of EB, blisters form below the cutaneous basement membrane at the level of the anchoring fibrils, which are composed of type VII c...

متن کاملA "late-but-fitter revertant cell" explains the high frequency of revertant mosaicism in epidermolysis bullosa
Revertant mosaicism, or "natural gene therapy", is the phenomenon in which germline mutations are corrected by somatic events. In recent years, revertant mosaicism has been identified in all major types of epidermolysis bullosa, the group of heritable blistering disorders caused by mutations in the genes encoding epidermal adhesion proteins. Moreover, revertant mosaicism appears to be present i...
