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]
RNU4-5P (HGNC:10198): (RNA, U4 small nuclear 5, pseudogene)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 24, 2023The c.1735A>G (p.I579V) alteration is located in exon 19 (coding exon 19) of the XPNPEP1 gene. This alteration results from a A to G substitution at nucleotide position 1735, causing the isoleucine (I) at amino acid position 579 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
