Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1

The NM_000285.4(PEPD):c.1163G>A(p.Arg388His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00413 in 1,548,190 control chromosomes in the GnomAD database, including 217 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R388C) has been classified as Uncertain significance.

Genes affected

PEPD (HGNC:8840): (peptidase D) This gene encodes a member of the peptidase family. The protein forms a homodimer that hydrolyzes dipeptides or tripeptides with C-terminal proline or hydroxyproline residues. The enzyme serves an important role in the recycling of proline, and may be rate limiting for the production of collagen. Mutations in this gene result in prolidase deficiency, which is characterized by the excretion of large amount of di- and tri-peptides containing proline. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]
