Erythrokeratodermia represents a group of rare genetic diseases characterized through disorders of keratinization. Clinically, they are presenting themselves with erythematous and hyperkeratosic lesions that can be persistent or variable as to their aspect and localization. They were classified in
A large pedigree with erythrokeratodermia variabilis (EKV) and erythema gyratum repens-like lesions is described. Clinical, laboratory, and histologic findings of this family are presented. The differential diagnoses of the following dermatoses with an erythematous and a hyperkeratotic component are
Erythrokeratodermia figurata variabilis (EKV) is a rare disorder of cornification inherited as an autosomal dominant trait. Genetic linkage to the Rh locus on chromosome 1 has been recently documented. In 1957, Sommacal and Schnyder reported on a family with 14 affected members. We have reexamined
Erythrokeratodermia variabilis (EKV) is a rare autosomal dominant genodermatosis with disturbed epidermal differentiation. Its clinical picture varies from transient, fast moving erythema to persistent brown hyperkeratoses. The gene defect in EKV was recently located on the short arm of chromosome 1
Erythrokeratodermia variabilis (EKV) is a rare autosomal dominant human genodermatosis. Its clinical appearance varies from transient, fast moving erythemas to persistent brown hyperkeratoses. So far, several mutations in the Cx31 or Cx30.3 gene have been reported to cause EKV in humans. We have
Erythrokeratodermia variabilis et progressiva (EKVP, OMIM 133200) is a rare hereditary disorder characterized by varies from transient, fast moving erythema to persistent brown hyperkeratotic plaques. Recently, mutations in the genes gap junction alpha 1 gene (GJA1), GJB3, and GJB4 The patient is a 5-year-old boy. There was no family history of the similar skin eruptions. The erythema with scales appeared on his head, face and neck at 1 month of birth. The erythematous hyperkeratotic plaques spread symmetrically. There was no follicular components. The eruption was chronic and
Erythrokeratodermia variabilis (EKV) is a skin disorder characterized by variable (transient) erythemas and fixed keratosis. The disorder maps to chromosome 1p34-35, a location that contains the GJB3 gene encoding the gap junction protein connexin 31. Until now, only heterozygote mutations in the
Erythrokeratodermia variabilis (EKV) is an autosomal dominant keratinization disorder characterized by migratory erythematous lesions and fixed keratotic plaques. All families with EKV show mapping to chromosome 1p34-p35, and mutations in the gene for connexin 31 (Cx31) have been reported in some
Genetic investigation of inherited skin disorders has informed the understanding of skin self-renewal, differentiation, and barrier function. Erythrokeratodermia variabilis et progressiva (EKVP) is a rare, inherited skin disease that is characterized by transient figurate patches of erythema,
Erythrokeratodermias are a clinically heterogeneous group of rare autosomal dominant disorders of cornification with overlapping features including hyperkeratosis and erythema. We ascertained five extended pedigrees with different phenotypes for a linkage study. Three families presented with
The ichthyoses are a heterogeneous group of disorders with both inherited and acquired forms. Clinical presentation, pattern of inheritance, and laboratory evaluation may establish a precise diagnosis, which can assist in prognosis and genetic counseling. Congenital autosomal recessive ichthyosis
Heritable disorders of cornification form a large, clinically and genetically heterogeneous group. Recent advances in molecular genetics provide for the first time the opportunity to reliably classify some of these disorders based on their underlying etiology. Many rare phenotypes, however, still
Intercellular channels in skin are a complex and functionally diverse system formed by at least eight connexins (Cx). Our recent molecular studies implicating Cx defects in inherited skin disorders emphasize the critical role of this signaling pathway in epidermal differentiation.
OBJECTIVE
The autosomal dominant spinocerebellar ataxias (SCAs) are a complex group of neurodegenerative disorders with significant genetic heterogeneity. Despite the identification of 20 SCA genes, the cause of the disorder in a significant proportion of families with SCA remains unexplained. In
