Genes affected

DPEP2 (HGNC:23028): (dipeptidase 2) DPEP2 belongs to the membrane-bound dipeptidase (EC 3.4.13.19) family. These enzymes hydrolyze a variety of dipeptides, including leukotriene D4, the beta-lactam ring of some antibiotics, and cystinyl-bis-glycine (cys-bis-gly) formed during glutathione degradation (Habib et al., 2003 [PubMed 12738806]).[supplied by OMIM, Mar 2008]

The c.1300C>T (p.R434C) alteration is located in exon 11 (coding exon 10) of the DPEP2 gene. This alteration results from a C to T substitution at nucleotide position 1300, causing the arginine (R) at amino acid position 434 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
