Genes affected

PES1 (HGNC:8848): (pescadillo ribosomal biogenesis factor 1) This gene encodes a nuclear protein that contains a breast cancer associated gene 1 (BRCA1) C-terminal interaction domain. The encoded protein interacts with BOP1 and WDR12 to form the PeBoW complex, which plays a critical role in cell proliferation via pre-rRNA processing and 60S ribosomal subunit maturation. Expression of this gene may play an important role in breast cancer proliferation and tumorigenicity. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. Pseudogenes of this gene are located on the long arm of chromosome 4 and the short arm of chromosome 9. [provided by RefSeq, Aug 2011]

Collection Method: clinical testing

The c.1343G>A (p.G448E) alteration is located in exon 12 (coding exon 12) of the PES1 gene. This alteration results from a G to A substitution at nucleotide position 1343, causing the glycine (G) at amino acid position 448 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
