Genes affected

SLC30A7 (HGNC:19306): (solute carrier family 30 member 7) Zinc functions as a cofactor for numerous enzymes, nuclear factors, and hormones and as an intra- and intercellular signal ion. Members of the zinc transporter (ZNT)/SLC30 subfamily of the cation diffusion facilitator family, such as SLC30A7, permit cellular efflux of zinc (Seve et al., 2004 [PubMed 15154973]).[supplied by OMIM, Mar 2008]

The c.565C>G (p.H189D) alteration is located in exon 6 (coding exon 6) of the SLC30A7 gene. This alteration results from a C to G substitution at nucleotide position 565, causing the histidine (H) at amino acid position 189 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
