Genes affected
SLC39A4 (HGNC:17129): (solute carrier family 39 member 4) This gene encodes a member of the zinc/iron-regulated transporter-like protein (ZIP) family. The encoded protein localizes to cell membranes and is required for zinc uptake in the intestine. Mutations in this gene result in acrodermatitis enteropathica. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2013]

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 374 of the SLC39A4 protein (p.Gly374Arg). This variant is present in population databases (rs121434289, gnomAD 0.005%). This missense change has been observed in individual(s) with acrodermatitis enteropathica (PMID: 12068297, 26351177). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 3539). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects SLC39A4 function (PMID: 14709598). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
