Genes affected

PRR5 (HGNC:31682): (proline rich 5) This gene encodes a protein with a proline-rich domain. This gene is located in a region of chromosome 22 reported to contain a tumor suppressor gene that may be involved in breast and colorectal tumorigenesis. The protein is a component of the mammalian target of rapamycin complex 2 (mTORC2), and it regulates platelet-derived growth factor (PDGF) receptor beta expression and PDGF signaling to Akt and S6K1. Alternative splicing and the use of alternative promoters results in transcripts encoding different isoforms. Read-through transcripts from this gene into the downstream Rho GTPase activating protein 8 (ARHGAP8) gene also exist, which led to the original description of PRR5 and ARHGAP8 being a single gene. [provided by RefSeq, Nov 2010]

PRR5 links:

PRR5-ARHGAP8 (HGNC:34512): (PRR5-ARHGAP8 readthrough) The PRR5-ARHGAP8 mRNA is an infrequent but naturally occurring read-through transcript of the neighboring proline rich 5, renal (PRR5) and Rho GTPase activating protein 8 (ARHGAP8) genes. The resulting fusion protein contains sequence identity with each individual gene product, and it includes domains characteristic of a RhoGAP protein. The significance of this read-through transcript and the function of its protein product have not yet been determined. [provided by RefSeq, Nov 2010]

The c.430T>G (p.F144V) alteration is located in exon 7 (coding exon 6) of the PRR5 gene. This alteration results from a T to G substitution at nucleotide position 430, causing the phenylalanine (F) at amino acid position 144 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
