Genes affected
SLC30A7 (HGNC:19306): (solute carrier family 30 member 7) Zinc functions as a cofactor for numerous enzymes, nuclear factors, and hormones and as an intra- and intercellular signal ion. Members of the zinc transporter (ZNT)/SLC30 subfamily of the cation diffusion facilitator family, such as SLC30A7, permit cellular efflux of zinc (Seve et al., 2004 [PubMed 15154973]).[supplied by OMIM, Mar 2008]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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. This variant has not been reported in the literature in individuals affected with SLC30A7-related conditions. This variant is present in population databases (rs529720665, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 3 of the SLC30A7 protein (p.Pro3Thr). -
