Genes affected
PREP (HGNC:9358): (prolyl endopeptidase) The protein encoded by this gene is a cytosolic prolyl endopeptidase that cleaves peptide bonds on the C-terminal side of prolyl residues within peptides that are up to approximately 30 amino acids long. Prolyl endopeptidases have been reported to be involved in the maturation and degradation of peptide hormones and neuropeptides. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2022The c.1510A>G (p.I504V) alteration is located in exon 12 (coding exon 12) of the PREP gene. This alteration results from a A to G substitution at nucleotide position 1510, causing the isoleucine (I) at amino acid position 504 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
