Genes affected

XPNPEP1 (HGNC:12822): (X-prolyl aminopeptidase 1) This gene encodes the cytosolic form of a metalloaminopeptidase that catalyzes the cleavage of the N-terminal amino acid adjacent to a proline residue. The gene product may play a role in degradation and maturation of tachykinins, neuropeptides, and peptide hormones. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Nov 2009]

Ambry Genetics

Feb 02, 2024

The c.815G>C (p.G272A) alteration is located in exon 9 (coding exon 9) of the XPNPEP1 gene. This alteration results from a G to C substitution at nucleotide position 815, causing the glycine (G) at amino acid position 272 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
