Abstract:
Erythrokeratodermia variabilis is a rare autosomal dominant genodermatosis characterized by transient erythema and fixed hyperkeratotic plaques. The disorder is genetically heterogeneous and may be associated with the mutations in GJB3 and GJB4 genes encoding connexin (Cx)31 and Cx30.3, respectively. Recently great advancement has been made in the research of molecular genetics in erythrokeratodermia variabilis, including the gene location and structure, the structure and function of encoding proteins, the gene mutation and its effects, which will lay a sound foundation for gene diagnosis and therapy of erythrokeratodermia variabilis. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
