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 GeneticsOct 29, 2021The c.455G>A (p.S152N) alteration is located in exon 6 (coding exon 6) of the XPNPEP1 gene. This alteration results from a G to A substitution at nucleotide position 455, causing the serine (S) at amino acid position 152 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
