Figure 1 Patient exhibits blistering with scarring leading to pseudosyndactyly of the hands (A and B), which is a hallmark of the recessive form of DEB and fuses the digits into “mitten” hands and feet with severe loss of function.

Figure 2 Partial sequence of exon 74 of the COL7A1 gene revealed a single cytosine deletion in a heterozygous mode in the parents (A) and homozygous mode in their affected daughter (B). This frameshift mutation at codon 2090 (C) creates a stop codon at codon 2116, which may cause a truncated gene product.
