Description
  • SLC39A4 encodes the human zinc transporter hZIP4 which plays an important role in cellular zinc homeostasis. Defects in SLC39A4 result in the inherited condition acrodermatitis enteropathica, zinc deficiency type (AEZ; MIM:201100), caused by the inability to absorb dietary zinc from the duodenum and jejunum. Clinical features include growth retardation, immune system dysfunction, severe dermatitis and mental disorders (Schmitt et al. 2009).
