Although some ectodermal dysplasia syndromes have no known genetic etiology, the number of ectodermal dysplasia syndromes with an identifiable genetic basis is increasing. Alternative Names Anhidrotic ectodermal dysplasia; Christ-Siemens-Touraine syndrome Causes There are many different types of ectodermal dysplasia. Individuals affected by ectodermal dysplasia have abnormalities in different ectodermal structures. I have always had very few teeth due to having ectodermal dysplasia. Defective nuclear IKKα function in patients with ectodermal dysplasia with immune deficiency Stephane T. Ectodermal dysplasia is a large group of inherited disorders characterized by a primary defect in hair, teeth, nails or sweat gland function, in addition to another abnormality in a tissue of ectodermal origin, e. Missing Teeth In many of the ectodermal dysplasias, affected individuals many have missing teeth (hypodontia). They classified the conditions according to the ectodermal structures involved and gave a number to each ectodermal derivative (hair is 1, teeth are 2, nails are 3, sweat gland function is 4); they identified 10 different subgroups for the EDs (for example, 1-2-3-4, 1-2-3). 1-3 In the absence of teeth, the alveolar ridge is compromised, making a removable prosthesis difficult to wear. Approximately 150 such diseases have been described in humans, but to date there are only three types with defined mutations in canines. Dentists should interact with pediatricians and neonatologists early in. All affected individuals displayed hypodontia with conical teeth, as well as various degrees of scalp hypotrichosis that was most prominent on the anterior scalp. Those with the condition usually have absent teeth (hypodontia) or malformed teeth. Ectodermal dysplasia with ectrodactyly and syndactyly are prominent features of this syndrome. Hypodontia of the primary and permanent dentition is the most com-mon oral finding. View Ectodermal Dysplasia Research Papers on Academia. Ectrodactyly, Ectodermal dysplasia, and Cleft lip-cleft palate (EEC) syndrome is a rare ectodermal dysplasia presenting with various combinations of its three components. net dictionary. Ectodermal dysplasias (EDs) are a heterogeneous group of disorders characterized by developmental dystrophies of ectodermal structures, such as hypohidrosis, hypotrichosis, onychodysplasia and hypodontia or anodontia. home / study / science / biology / biology questions and answers / Anhidrotic Ectodermal Dysplasia Is An X-linked Recessive Disorder In Humans Characterized By Show transcribed image text Anhidrotic ectodermal dysplasia is an X-linked recessive disorder in humans characterized by small teeth, no sweat glands, and sparse body hair. Is it possible that my husband is a carrier or that my future children could have the condition or be carriers? I'm very confused and worried. Premature neonates and infants with cleft palates have unique dental prob- lems.
