Abstract EN
Suboptimal dietary zinc (Zn2+) intake is increasingly appreciated as an important public health issue.
Zn2+ is an essential mineral, and infants are particularly vulnerable to Zn2+ deficiency, as they require large amounts of Zn2+ for their normal growth and development.
Although term infants are born with an important hepatic Zn2+ storage, adequate Zn2+ nutrition of infants mostly depends on breast milk or formula feeding, which contains an adequate amount of Zn2+ to meet the infants’ requirements.
An exclusively breast-fed 6 months old infant suffering from Zn2+ deficiency caused by an autosomal dominant negative G87R mutation in the Slc30a2 gene (encoding for the zinc transporter 2 (ZnT-2)) in the mother is reported.
More than 20 zinc transporters characterized up to date, classified into two families (Slc30a/ZnT and Slc39a/Zip), reflect the complexity and importance of maintaining cellular Zn2+ homeostasis and dynamics.
The role of ZnTs is to reduce intracellular Zn2+ by transporting it from the cytoplasm into various intracellular organelles and by moving Zn2+ into extracellular space.
Zips increase intracellular Zn2+ by transporting it in the opposite direction.
Thus the coordinated action of both is essential for the maintenance of Zn2+ homeostasis in the cytoplasm, and accumulating evidence suggests that this is also true for the secretory pathway of growth hormone.
