Utility of whole exome sequencing in detecting novel compound heterozygous mutations in COL7A1 among families with severe recessive Dystrophic Epidermolysis Bullosa in India - implications on diagnosis, prognosis and prenatal testing

Epidermolysis Bullosa (EB) encompasses a number of genetic conditions caused by mutations in genes involved in the formation of basement membrane resulting in blistering of the epidermis on trauma or pressure. At least 18 genes and 30 distinct subtypes of the disease are presently known[1]. Here-in, we report two un-related children with recessive dystrophic EB (RDEB) with novel compound heterozygous variations in collagen VII, one of whom had a fatal outcome and the other with a better sequel.
