Genes affected

STEAP4 (HGNC:21923): (STEAP4 metalloreductase) The protein encoded by this gene belongs to the STEAP (six transmembrane epithelial antigen of prostate) family, and resides in the golgi apparatus. It functions as a metalloreductase that has the ability to reduce both Fe(3+) to Fe(2+) and Cu(2+) to Cu(1+), using NAD(+) as acceptor. Studies in mice and human suggest that this gene maybe involved in adipocyte development and metabolism, and may contribute to the normal biology of the prostate cell, as well as prostate cancer progression. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2011]

Collection Method: clinical testing

The c.710G>A (p.R237H) alteration is located in exon 3 (coding exon 2) of the STEAP4 gene. This alteration results from a G to A substitution at nucleotide position 710, causing the arginine (R) at amino acid position 237 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
