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.91C>A (p.P31T) alteration is located in exon 2 (coding exon 2) of the TGFB1I1 gene. This alteration results from a C to A substitution at nucleotide position 91, causing the proline (P) at amino acid position 31 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
