Acrodermatitis Enteropathica: Causes, Symptoms, Diagnosis, and Treatment


Acrodermatitis enteropathica is a rare genetic disorder characterized by the impaired absorption of zinc from the diet, leading to zinc deficiency. This condition primarily affects the skin, causing characteristic skin rashes and other symptoms. In this article, we will explore the causes, symptoms, diagnosis, and treatment options for acrodermatitis enteropathica.


Acrodermatitis enteropathica is caused by mutations in the SLC39A4 gene, which is responsible for the production of a protein involved in zinc transport. These mutations impair the absorption of zinc in the intestines, leading to zinc deficiency and the associated symptoms.


The symptoms of acrodermatitis enteropathica can vary but often include:

  • Red and inflamed skin lesions, especially around the mouth, nose, and genital area
  • Scaly and crusted patches on the skin
  • Frequent skin infections
  • Hair loss
  • Diarrhea
  • Delayed growth and development in infants


Diagnosing acrodermatitis enteropathica typically involves a combination of clinical evaluation, family history assessment, and laboratory tests. Blood tests can reveal low levels of zinc, and genetic testing can confirm the presence of mutations in the SLC39A4 gene.


The primary treatment for acrodermatitis enteropathica involves zinc supplementation to correct the zinc deficiency. This usually involves high-dose oral zinc supplements or zinc injections under medical supervision. Additionally, maintaining a diet rich in zinc-rich foods, such as meat, shellfish, legumes, and whole grains, is crucial for ongoing management.

Supportive Measures:

In addition to zinc supplementation, other supportive measures can help manage the symptoms and complications of acrodermatitis enteropathica:

  • Topical treatments: Applying zinc-based creams or ointments to affected areas can help soothe and heal the skin.
  • Antibiotic therapy: In cases where secondary infections occur, antibiotics may be prescribed to address bacterial infections.
  • Dietary counseling: Working with a registered dietitian can ensure a well-balanced diet that includes adequate zinc and other essential nutrients.
  • Regular follow-up: Ongoing monitoring and follow-up with a healthcare professional are necessary to assess zinc levels and overall health.


Acrodermatitis enteropathica is a rare genetic disorder characterized by zinc deficiency, resulting in skin rashes and other symptoms. Early diagnosis and prompt treatment with zinc supplementation are essential for managing the condition and preventing complications. Regular monitoring and follow-up with healthcare professionals are important for ongoing management and support.
