Genes affected

SLC39A13 (HGNC:20859): (solute carrier family 39 member 13) This gene encodes a member of the LIV-1 subfamily of the ZIP transporter family. The encoded transmembrane protein functions as a zinc transporter. Mutations in this gene have been associated with the spondylocheiro dysplastic form of Ehlers-Danlos syndrome. Alternate transcript variants have been found for this gene. [provided by RefSeq, Jan 2016]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jul 08, 2022	This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 212 of the SLC39A13 protein (p.Arg212Gln). This variant is present in population databases (rs200490683, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with SLC39A13-related conditions. ClinVar contains an entry for this variant (Variation ID: 469535). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -

The c.635G>A (p.R212Q) alteration is located in exon 5 (coding exon 4) of the SLC39A13 gene. This alteration results from a G to A substitution at nucleotide position 635, causing the arginine (R) at amino acid position 212 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
