Genes affected

SLC39A1 (HGNC:12876): (solute carrier family 39 member 1) This gene encodes a member of the zinc-iron permease family. The encoded protein is localized to the cell membrane and acts as a zinc uptake transporter. This gene has been linked to prostate cancer, breast cancer, and Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.21360469).

The c.170C>A (p.A57D) alteration is located in exon 3 (coding exon 1) of the SLC39A1 gene. This alteration results from a C to A substitution at nucleotide position 170, causing the alanine (A) at amino acid position 57 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
