Transient neonatal zinc deficiency occurs in breast-fed infants as a consequence of low milk zinc concentration in their nursing mothers, which cannot be corrected by maternal zinc supplementation. A large amount of zinc, an essential trace mineral, is required for normal growth particularly in infants, and breast milk normally contains adequate zinc to meet the requirement for infants up to 4 to 6 months of age. Zinc deficiency can lead to dermatitis, alopecia, decreased growth, and impaired immune function. The disorder shows autosomal dominant inheritance with incomplete penetrance (summary by Chowanadisai et al., 2006).
Some aspects of TNZD resemble the more severe disorder acrodermatitis enteropathica (AEZ; 201100), an autosomal recessive disorder caused by mutation in the zinc transporter SLC39A4 (607059). However, infants with transient neonatal zinc deficiency do not require zinc supplementation following weaning and have normal zinc absorption, whereas those with AEZ require lifelong zinc supplementation (summary by Chowanadisai et al., 2006).

MalaCards based summary : Zinc Deficiency, Transient Neonatal, also known as zinc deficiency, neonatal, due to low breast milk zinc, is related to acrodermatitis enteropathica, zinc-deficiency type and acrodermatitis. An important gene associated with Zinc Deficiency, Transient Neonatal is SLC30A2 (Solute Carrier Family 30 Member 2). Affiliated tissues include breast and skin, and related phenotypes are eczema and abnormality of the skin UniProtKB/Swiss-Prot : 75 Zinc deficiency, transient neonatal: A disorder occurring in breast-fed infants as a consequence of low milk zinc concentration in their nursing mothers, which cannot be corrected by maternal zinc supplementation.
