Genes affected
SLC39A2 (HGNC:17127): (solute carrier family 39 member 2) This gene encodes a member of the ZIP family of metal ion transporters. The encoded protein functions as a zinc transporter. Mutations in this gene may be associated with susceptibility to carotid artery disease. Multiple transcript variants have been described. [provided by RefSeq, Mar 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.462T>A (p.H154Q) alteration is located in exon 4 (coding exon 4) of the SLC39A2 gene. This alteration results from a T to A substitution at nucleotide position 462, causing the histidine (H) at amino acid position 154 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
