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]

The c.1845A>G (p.I615M) alteration is located in exon 20 (coding exon 20) of the XPNPEP1 gene. This alteration results from a A to G substitution at nucleotide position 1845, causing the isoleucine (I) at amino acid position 615 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
