Genes affected

STEAP3 (HGNC:24592): (STEAP3 metalloreductase) This gene encodes a multipass membrane protein that functions as an iron transporter. The encoded protein can reduce both iron (Fe3+) and copper (Cu2+) cations. This protein may mediate downstream responses to p53, including promoting apoptosis. Deficiency in this gene can cause anemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

Ambry Genetics

Dec 13, 2022

The c.151C>T (p.R51C) alteration is located in exon 3 (coding exon 2) of the STEAP3 gene. This alteration results from a C to T substitution at nucleotide position 151, causing the arginine (R) at amino acid position 51 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
