Identification of two missense mutations in the <i>SLC30A2/ZnT2</i> gene in the mother of a zinc-deficient infant.

<p>(<b>A</b>) Photograph of an affected infant with severe zinc deficiency. The dermatitis was erythematous and erosive, particularly around the infant's mouth. (<b>B</b>) Predicted topology of hZnT2 indicating the positions of the W152R and S296L substitutions found in this study. (<b>C</b>) Electropherograms showing SLC30A2/<i>ZnT2</i> mutations in the affected mother. W152R and S296L mutations were found at exons 4 and 7 on different alleles.
