Genes affected

PRUNE2 (HGNC:25209): (prune homolog 2 with BCH domain) The protein encoded by this gene belongs to the B-cell CLL/lymphoma 2 and adenovirus E1B 19 kDa interacting family, whose members play roles in many cellular processes including apotosis, cell transformation, and synaptic function. Several functions for this protein have been demonstrated including suppression of Ras homolog family member A activity, which results in reduced stress fiber formation and suppression of oncogenic cellular transformation. A high molecular weight isoform of this protein has also been shown to colocalize with Adaptor protein complex 2, beta-Adaptin and endodermal markers, suggesting an involvement in post-endocytic trafficking. In prostate cancer cells, this gene acts as a tumor suppressor and its expression is regulated by prostate cancer antigen 3, a non-protein coding gene on the opposite DNA strand in an intron of this gene. Prostate cancer antigen 3 regulates levels of this gene through formation of a double-stranded RNA that undergoes adenosine deaminase actin on RNA-dependent adenosine-to-inosine RNA editing. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015]

PRUNE2 links:

PCA3 (HGNC:8637): (prostate cancer associated 3) This gene produces a spliced, long non-coding RNA that is highly overexpressed in most types of prostate cancer cells and is used as a specific biomarker for this type of cancer. This gene is embedded in an intronic region of the prune2 gene on the opposite DNA strand. The transcript regulates prune2 levels through formation of a double-stranded RNA that undergoes adenosine deaminase acting on RNA-dependent adenosine-to-inosine RNA editing. In prostate cancer derived cells, overexpression of PCA induced downregulation of prune2, leading to decreased cell proliferation. Conversely, silencing in prostate cancer cells resulted in increased proliferation. Regulation of this gene appears to be sensitive to androgen-receptor activation, a molecular signature of prostate cancer. Alternative splicing results in multiple transcript variants.

The c.7855G>A (p.D2619N) alteration is located in exon 9 (coding exon 9) of the PRUNE2 gene. This alteration results from a G to A substitution at nucleotide position 7855, causing the aspartic acid (D) at amino acid position 2619 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
