From NCBI Gene: This gene encodes a nuclear polyglutamine-binding protein that is involved with transcription activation. The encoded protein contains a WW domain. Mutations in this gene have been found in patients with Renpenning syndrome 1 and other syndromes with X-linked mental retardation. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.[provided by RefSeq, Nov 2009]

Performance Comment

Significance Analysis of Microarray (SAM) was used to develop a 7-gene classifier. The overall prediction accuracy and sensitivity is 71% and 76%, respectively. The inclusion of the Gleason sum to the seven-gene classifier raised the prediction accuracy and sensitivity to 83% and 76% respectively This prognostic signature is closely associated with biochemical recurrence in patients after radical prostatectomy. The seven genes are: RRAGD, PQBP1, HIST1H2BC, ALDH1A2, TRIM22, RBPMS, HSPB8.
