A recurrent glycine substitution mutation, G2043R, in the type VII collagen gene (COL7A1) in dominant dystrophic epidermolysis bullosa

Abstract: Dystrophic epidermolysis bullosa (DEB) is caused by mutations in the type VII collagen gene (COL7A1). Nearly all cases of dominant DEB are caused by glycine substitution mutations occurring within the triple helical region of type VII collagen, and most of the mutations are unique to individual families. In this study, we identified a patient of Hispanic-Mexican origin with a mild form of DEB, which resulted from a de novo dominant glycine substitution, G2043R, in exon 73 of COL7A1. We also investigated a Scot… Show more

“…Most of the mutations are located immediately after the non-collagen segment of the center of the triple helix; 42 the G2043R mutation is the most commonly described. 36,41 Likewise it has already been demonstrated that the functional alteration of the anchoring fibrils depends on the location in which the glycine is substituted, 34,44 which in turn contributes to the clinical variability. As yet, there is no convincing explanation as to why the glycine substitution is an inherited dominant trait.…”

“…36,37 No centro da tripla hélice há pequeno segmento não coláge-no, o qual provavelmente dá flexibilidade à proteína. Posteriormente, no nível extracelular, ocorrerá com duas dessas moléculas uma fusão com perda do segmento NC-2, formando dímeros antiparalelos.…”
