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]

Ambry Genetics

Dec 20, 2023

The c.256G>A (p.E86K) alteration is located in exon 2 (coding exon 1) of the DPP3 gene. This alteration results from a G to A substitution at nucleotide position 256, causing the glutamic acid (E) at amino acid position 86 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
