Genes affected

STEAP2 (HGNC:17885): (STEAP2 metalloreductase) This gene is a member of the STEAP family and encodes a multi-pass membrane protein that localizes to the Golgi complex, the plasma membrane, and the vesicular tubular structures in the cytosol. A highly similar protein in mouse has both ferrireductase and cupric reductase activity, and stimulates the cellular uptake of both iron and copper in vitro. Increased transcriptional expression of the human gene is associated with prostate cancer progression. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

The c.738C>G (p.D246E) alteration is located in exon 3 (coding exon 2) of the STEAP2 gene. This alteration results from a C to G substitution at nucleotide position 738, causing the aspartic acid (D) at amino acid position 246 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
