Ectodermal dysplasia (ED) is a rare genetic disorder that affects various parts of the body, primarily those derived from the ectodermal germ layer during embryonic development. This condition can manifest in several types, each with its own distinct characteristics. In this article, we will explore the types, causes, symptoms, diagnostic tests, treatments, and drugs associated with ectodermal dysplasia in simple and accessible language.
Types of Ectodermal Dysplasia:
- Hypohidrotic Ectodermal Dysplasia (HED): This is the most common type of ED. People with HED have issues with sweat gland function, causing difficulty in regulating body temperature. They often have missing or abnormally shaped teeth and sparse hair.
- Hypohidrosis with Immune Deficiency (HED-ID): Similar to HED, but individuals also have an impaired immune system, making them more susceptible to infections.
- Anhidrotic Ectodermal Dysplasia with Immunodeficiency (EDA-ID): This type is characterized by the absence of sweat glands, leading to overheating, as well as immune system problems.
- Clouston Syndrome: This type primarily affects the hair, nails, and skin. People with Clouston syndrome typically have thick, curly hair and nail abnormalities.
- Hay-Wells Syndrome: This is a rare type of ED that causes skin problems, hair abnormalities, and cleft lip or palate.
- Rapp-Hodgkin Syndrome: Individuals with this type often have cleft lip or palate, as well as hair and skin issues.
- Ectrodactyly Ectodermal Dysplasia-Clefting (EEC) Syndrome: EEC syndrome combines ED with limb abnormalities and cleft lip or palate.
- Ellis-van Creveld Syndrome: This rare type affects the teeth, nails, and bones, leading to short stature and heart problems.
- AEC Syndrome (Ankyloblepharon-Ectodermal Defects-Cleft Lip/Palate): AEC syndrome involves abnormalities in the skin, hair, nails, and cleft lip or palate.
- Trichothiodystrophy: This type is associated with hair that is brittle and breaks easily, along with intellectual disabilities.
Causes of Ectodermal Dysplasia:
Ectodermal dysplasia is primarily caused by genetic mutations. These mutations can be inherited from one or both parents or occur spontaneously. Here are 20 potential genetic causes:
- EDA Gene Mutations: Mutations in the EDA gene are a common cause of HED.

- TP63 Gene Mutations: TP63 gene mutations can lead to Rapp-Hodgkin syndrome.
- PAX6 Gene Mutations: Mutations in the PAX6 gene can cause eye-related symptoms in some types of ED.
- GJB6 Gene Mutations: Mutations in the GJB6 gene are associated with some forms of HED.
- CTSC Gene Mutations: Mutations in the CTSC gene can lead to Ellis-van Creveld syndrome.
- CTNNB1 Gene Mutations: Mutations in the CTNNB1 gene are associated with some cases of EEC syndrome.
- ROR2 Gene Mutations: Mutations in the ROR2 gene can cause EEC syndrome.
- Cantú Syndrome: This rare genetic disorder is caused by mutations in the ABCC9 gene.
- GLI3 Gene Mutations: Mutations in the GLI3 gene can lead to some types of ED.
- CDH3 Gene Mutations: Mutations in the CDH3 gene can cause EEC syndrome.
- ERCC2 Gene Mutations: Mutations in the ERCC2 gene are associated with trichothiodystrophy.
- PIR Gene Mutations: Mutations in the PIR gene can cause some forms of ED.
- KRT5 Gene Mutations: Mutations in the KRT5 gene are linked to Clouston syndrome.
- JAG1 Gene Mutations: Mutations in the JAG1 gene can cause some types of ED.
