Genes affected

ENPEP (HGNC:3355): (glutamyl aminopeptidase) The ENPEP gene encodes glutamyl aminopeptidase, a type II integral membrane protein with an extracellular zinc-binding domain. This protein can upregulate blood pressure by cleaving the N-terminal aspartate from angiotensin II, and can regulate blood vessel formation and enhance tumorigenesis in some tissues. Along with ANPEP and DPP4, ENPEP was found to be a candidate co-receptor for the coronavirus SARS-CoV-2, which causes COVID-19. [provided by RefSeq, Apr 2020]

Collection Method: clinical testing

The c.721G>T (p.A241S) alteration is located in exon 2 (coding exon 2) of the ENPEP gene. This alteration results from a G to T substitution at nucleotide position 721, causing the alanine (A) at amino acid position 241 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
