Genes affected

DPP3 (HGNC:3008): (dipeptidyl peptidase 3) This gene encodes a protein that is a member of the M49 family of metallopeptidases. This cytoplasmic protein binds a single zinc ion with its zinc-binding motif (HELLGH) and has post-proline dipeptidyl aminopeptidase activity, cleaving Xaa-Pro dipeptides from the N-termini of proteins. Increased activity of this protein is associated with endometrial and ovarian cancers. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Feb 2012]

Collection Method: clinical testing

The c.44C>G (p.S15C) alteration is located in exon 2 (coding exon 1) of the DPP3 gene. This alteration results from a C to G substitution at nucleotide position 44, causing the serine (S) at amino acid position 15 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
