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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2024The c.860C>T (p.A287V) alteration is located in exon 10 (coding exon 10) of the XPNPEP1 gene. This alteration results from a C to T substitution at nucleotide position 860, causing the alanine (A) at amino acid position 287 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
