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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.25G>C (p.D9H) alteration is located in exon 1 (coding exon 1) of the SLC30A7 gene. This alteration results from a G to C substitution at nucleotide position 25, causing the aspartic acid (D) at amino acid position 9 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
