Acrodermatitis enteropathica zinc deficiency type; AEZ; Brandt syndrome; Danbolt-Cross syndrome; AE

== '''Definition''' ==
Acrodermatitis enteropathica (AE) is a disorder of [[zinc]] metabolism that can either be inherited or acquired. Both forms lead to the '''inability to absorb zinc from the intestine'''.
The lack of zinc can cause skin [[inflammation]] with a rash (pustular [[dermatitis]]) around the mouth and/or [[anus]]; [[diarrhea]]; and abnormal nails (nail [[dystrophy]]). Irritability and emotional disturbances can also occur.

== '''Cause''' ==
* The inherited form is caused by mutations in the '''SLC39A4 gene'''.
* The acquired form can result from diets lacking the appropriate amount of zinc.

== '''Inheritance''' ==
[[File:Autorecessive.svg|thumb|right|Autosomal recessive inheritance, a 25% chance]]
It is inherited in an [[autosomal recessive]] pattern.

== '''Signs and symptoms''' ==
Individuals with acrodermatitis enteropathica may present with the following:
* Blistering of skin
* Dry skin
* Emotional lability
* [[Glossitis]]
* [[Pustule]]
* [[Alopecia]] (loss of hair from the scalp, eyebrows, and eyelashes) may occur. Skin lesions may be secondarily infected by bacteria such as [[Staphylococcus aureus]] or fungi such as [[Candida albicans]]. These skin lesions are accompanied by [[diarrhea]].

== '''Clinical presentation''' ==
For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed.

'''80%-99% of people have these symptoms'''
* Abnormal [[blistering]] of the skin(Blistering, generalized)
* Abnormal eyebrow morphology(Abnormality of the eyebrow)
* Alopecia(Hair loos)
* Cerebral cortical atrophy(Decrease in size of the outer layer of the brain due to loss of brain cells)
* Chronic [[diarrhea]]
* Dry skin
* [[Erythema]]
* Malabsorption(Intestinal malabsorption)
* Pustule(Pimple)
* Short stature(Decreased body height)

'''30%-79% of people have these symptoms'''
* [[Blepharitis]](Inflammation of eyelids)
* [[Cheilitis]](Inflammation of the lips)
* [[Conjunctivitis]](Pink eye)
* Emotional lability(Emotional instability)
* Failure to thrive(Faltering weight)
* Furrowed tongue(Grooved tongue)
* [[Glossitis]](Inflammation of the tongue)
* [[Paronychia]]
* Photophobia(Extreme sensitivity of the eyes to light)
* Ridged fingernail(Longitudinally grooved fingernails)
* Ridged nail(Grooved nails)
* Skin ulcer(Open skin sore)

'''5%-29% of people have these symptoms'''
* [[Anorexia]]
* Corneal erosion(Damage to outer layer of the cornea of the eye)
* Poor appetite(Decreased appetite)
* Visual impairment(Impaired vision)
* Weight loss

== '''Diagnosis''' ==
The diagnosis of an individual with acrodermatitis enteropathica includes each of the following:
* [[Plasma]] zinc level (lab)
* [[Light microscopy]](skin [[biopsy]])
* [[Electron microscopy]] (histology)

== '''Treatment''' ==
* Acrodermatitis enteropathica without treatment is fatal, and affected individuals may die within a few years.
* There is no cure for the condition.
* '''Supplemental zinc''' usually eliminates the symptoms of acrodermatitis enteropathica.
