Genes affected
DPEP1 (HGNC:3002): (dipeptidase 1) The protein encoded by this gene is a kidney membrane enzyme involved in the metabolism of glutathione and other similar proteins by dipeptide hydrolysis. The encoded protein is known to regulate leukotriene activity by catalyzing the conversion of leukotriene D4 to leukotriene E4. This protein uses zinc as a cofactor and acts as a disulfide-linked homodimer. [provided by RefSeq, Dec 2020]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2024The c.736C>T (p.R246C) alteration is located in exon 7 (coding exon 6) of the DPEP1 gene. This alteration results from a C to T substitution at nucleotide position 736, causing the arginine (R) at amino acid position 246 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
