Clinical and allelic heterogeneity in dystrophic epidermolysis bullosa- lessons from an Indian cohort.

Background: Dystrophic epidermolysis bullosa (DEB) is due to variation in the COL7A1 gene. The clinical phenotype and severity depends on the type of variation and domain of the affected protein.

Objectives: To characterize the spectrum of COL7A1 variations in a cohort of DEB patients from India, to correlate these findings with clinical phenotypes and to establish a genotype-phenotype correlation.

Clinical heterogeneity in epidermolysis bullosa simplex with plectin (PLEC) mutations-A study of six unrelated families from India.

Epidermolysis bullosa simplex (EBS) with plectin mutations is a very rare subtype of EB usually associated with pyloric atresia (PA) or muscular dystrophy (MD). We report six unrelated children between ages 4 and 14 years from India with varied clinical manifestations. Only one had PA, and none has developed MD to date.
