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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.649G>A (p.V217I) alteration is located in exon 5 (coding exon 5) of the SLC30A2 gene. This alteration results from a G to A substitution at nucleotide position 649, causing the valine (V) at amino acid position 217 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
