Full Answer
Although Thurnam published the first report of a patient with ectodermal dysplasia in 1848, the term ectodermal dysplasia was not coined until 1929 by Weech. The ectodermal dysplasias are congenital, diffuse, and nonprogressive. To date, more than 192 distinct disorders have been described.
Pure ectodermal dysplasias are manifested by defects in ectodermal structures alone, while ectodermal dysplasia syndromes are defined by the combination of ectodermal defects in association with other anomalies.
The tissues primarily involved are the skin and its appendages (hair follicles, eccrine glands, sebaceous glands, and, nails) and teeth. Although Thurnam published the first report of a patient with ectodermal dysplasia in 1848, the term ectodermal dysplasia was not coined until 1929 by Weech. [1]
A heterozygous mutation in the TRAF6 gene has been described in a patient with hypohidrotic ectodermal dysplasia. Hidrotic ectodermal dysplasia (Clouston syndrome), which is an autosomal dominant disorder, is caused by mutations in GJB6, which encodes connexin 30, a component of intercellular gap junctions.
In 1838, Wedderburn documented ectodermal dysplasia in a letter to Charles Darwin, describing a case of 10 Hindu male family members. Thurnam in 1848 reported 2 cases of hypohidrotic form. Similar cases were reported by Guilford and Hutchinson in 1883 and 1886 respectively.
The ectodermal dysplasias (EDs) are a heterogeneous group of nearly 100 inherited disorders characterized by anomalies in at least two of the structures derived from the embryonic ectoderm, with at least one involving the skin appendages (hair, nails, sweat glands) or teeth.
What is the cause of ectodermal dysplasia? The different types of ectodermal dysplasia are caused by the mutation or deletion of certain genes located on different chromosomes. Because ectodermal dysplasias are caused by a genetic defect, they may be inherited or passed on down the family line.
Hypohidrotic ectodermal dysplasia (HED) is a rare inherited multisystem disorder that belongs to the group of diseases known as ectodermal dysplasias. Ectodermal dysplasias typically affect the hair, teeth, nails, sweat glands, and/or skin.
The tissues primarily involved are the skin and its appendages (hair follicles, eccrine glands, sebaceous glands, and, nails) and teeth. Although Thurnam published the first report of a patient with ectodermal dysplasia in 1848, the term ectodermal dysplasia was not coined until 1929 by Weech.
There are many types of ectodermal dysplasia (ED), but all of them affect at least two of the ectodermal structures — the skin, hair, nails, teeth, mucous membranes and sweat glands.
Ectodermal Dysplasia Can Also Cause the Following Medical Issues: Cleft lip and palate. Allergies and immunodeficiencies, such as increased frequencies of asthma, allergies, eczema or rhinitis symptoms. Gastrointestinal issues, such as constipation.
Oral rehabilitation of patients with ectodermal dysplasia is necessary to improve sagital and vertical skeletal relationships during craniofacial growth and development as well as esthetics, speech, and masticatory efficiency. The most common treatment plan is removable prosthesis.
Unfortunately, there is no cure for ectodermal dysplasia. Instead, the goal is to successfully manage the symptoms so that the individual can lead a healthy life and have a good quality of life. Because the symptoms vary depending on the type of ectodermal dysplasia, the treatment plan will vary with each person too.
Abstract. A case is reported of hereditary ectodermal dysplasia with corneal involvement associated with polyendocrinopathy and pernicious anaemia. The presence of autoantibodies to various endocrine organs and ocular tissues is confirmed. This suggests that ectodermal dysplasia may be an autoimmune disease.
An estimated 3.5 of 10,000 people are affected by ectodermal dysplasia. Ectodermal dysplasias are considered “rare” conditions because they affect less than 200,000 people in the United States. This rarity makes an official study to determine numbers difficult and costly.
Anhidrotic ectodermal dysplasia with immune deficiency (EDA-ID) is a form of ectodermal dysplasia, which is a group of conditions characterized by abnormal development of ectodermal tissues including the skin, hair, teeth, and sweat glands.
Although Thurnam published the first report of a patient with ectodermal dysplasia in 1848 , the term ectodermal dysplasia was not coined until 1929 by Weech. [ 1] The ectodermal dysplasias are congenital, diffuse, and nonprogressive. To date, more than 192 distinct disorders have been described.
The 3 most commonly recognized entities are (1) ectodermal dysplasia, ectrodactyly, and clefting (EEC) syndrome [ 10] ; (2) Hay-Wells syndrome or ankyloblepharon, ectodermal dysplasia, and cleft lip/palate (AEC) syndrome; and (3) Rapp-Hodgkin syndrome, all of which are caused by mutations in the TP63 gene. See the images below.
The ectodermal dysplasias (EDs) comprise a large, heterogeneous group of inherited disorders that are defined by primary defects in the development of 2 or more tissues derived from embryonic ectoderm. The tissues primarily involved are the skin and its appendages (hair follicles, eccrine glands, sebaceous glands, and, nails) and teeth. Although Thurnam published the first report of a patient with ectodermal dysplasia in 1848, the term ectodermal dysplasia was not coined until 1929 by Weech. [ 1]
Nail dystrophy: Abnormal nail plate formation may result in brittle, thin, ridged, or grossly deformed nails. Although some ectodermal dysplasia syndromes have no known genetic etiology, the number of ectodermal dysplasia syndromes with an identifiable genetic basis is increasing.
Hypohidrotic ectodermal dysplasia may manifest as scaling and erythema at birth. EEC syndrome and other related ectrodactyly syndromes (eg, acro-dermato-ungual-lacrimal-tooth [ADULT] syndrome and limb-mammary syndrome) are usually recognized at birth as a result of the characteristic limb deformities.
Eccrine defects: Eccrine sweat glands may be absent or sparse and rudimentary, particularly in patients with hypohidrotic ectodermal dysplasia. [ 11, 12] Other secretory gland defects: Hypoplasia of the salivary, sebaceous, and lacrimal glands may occur.
Life span can be affected in some rare types of ectodermal dysplasia. For example, patients with ectodermal dysplasia with immunodeficiency are at risk for significant morbidity and mortality related to recurrent infections and failure to thrive. Previous.
