Genes affected

DPEP3 (HGNC:23029): (dipeptidase 3) This gene encodes a membrane-bound glycoprotein from the family of dipeptidases involved in hydrolytic metabolism of various dipeptides, including penem and carbapenem beta-lactam antibiotics. This gene is located on chromosome 16 in a cluster with another member of this family. Alternatively spliced transcript variants that encode different isoforms have been found for this gene.

Ambry Genetics

Sep 27, 2022

The c.760T>C (p.W254R) alteration is located in exon 4 (coding exon 4) of the DPEP3 gene. This alteration results from a T to C substitution at nucleotide position 760, causing the tryptophan (W) at amino acid position 254 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
