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.

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 09, 2024 | The c.56C>T (p.P19L) alteration is located in exon 2 (coding exon 1) of the STEAP2 gene. This alteration results from a C to T substitution at nucleotide position 56, causing the proline (P) at amino acid position 19 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
