SLC39A4
Chr 8ARsolute carrier family 39 member 4
Also known as: AEZ, AWMS2, ZIP4
This protein functions as a selective zinc transporter that mediates zinc uptake in the intestinal tract, playing an essential role in dietary zinc absorption. Mutations cause acrodermatitis enteropathica, a disorder characterized by zinc deficiency affecting the skin, gastrointestinal system, and immune function. The condition follows autosomal recessive inheritance and typically presents in early infancy.

Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
