Genes affected

PWP1 (HGNC:17015): (PWP1 homolog, endonuclein) The protein encoded by this gene contains several WD-40 repeats and is found mostly in the nucleus. The expression and localization of this protein are cell cycle dependent. Expression of this gene is upregulated in pancreatic adenocarcinoma. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

The c.356C>T (p.T119M) alteration is located in exon 4 (coding exon 4) of the PWP1 gene. This alteration results from a C to T substitution at nucleotide position 356, causing the threonine (T) at amino acid position 119 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
