Genes affected

TGFB1I1 (HGNC:11767): (transforming growth factor beta 1 induced transcript 1) This gene encodes a coactivator of the androgen receptor, a transcription factor which is activated by androgen and has a key role in male sexual differentiation. The encoded protein is thought to regulate androgen receptor activity and may have a role to play in the treatment of prostate cancer. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

The c.265G>A (p.G89R) alteration is located in exon 4 (coding exon 4) of the TGFB1I1 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the glycine (G) at amino acid position 89 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
