Genes affected

SLC30A2 (HGNC:11013): (solute carrier family 30 member 2) The protein encoded by this gene is a zinc transporter that acts as a homodimer. The encoded protein plays a role in secreting zinc into breast milk. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2015]

The c.577G>C (p.G193R) alteration is located in exon 5 (coding exon 5) of the SLC30A2 gene. This alteration results from a G to C substitution at nucleotide position 577, causing the glycine (G) at amino acid position 193 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
