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]

Collection Method: clinical testing

The c.602C>G (p.A201G) alteration is located in exon 4 (coding exon 4) of the SLC39A2 gene. This alteration results from a C to G substitution at nucleotide position 602, causing the alanine (A) at amino acid position 201 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
