Genes affected

STEAP1 (HGNC:11378): (STEAP family member 1) This gene is predominantly expressed in prostate tissue, and is found to be upregulated in multiple cancer cell lines. The gene product is predicted to be a six-transmembrane protein, and was shown to be a cell surface antigen significantly expressed at cell-cell junctions. [provided by RefSeq, Jul 2008]

The c.908T>C (p.I303T) alteration is located in exon 5 (coding exon 4) of the STEAP1 gene. This alteration results from a T to C substitution at nucleotide position 908, causing the isoleucine (I) at amino acid position 303 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
