Genes affected

DPP4 (HGNC:3009): (dipeptidyl peptidase 4) The DPP4 gene encodes dipeptidyl peptidase 4, which is identical to adenosine deaminase complexing protein-2, and to the T-cell activation antigen CD26. It is an intrinsic type II transmembrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. Dipeptidyl peptidase 4 is highly involved in glucose and insulin metabolism, as well as in immune regulation. This protein was shown to be a functional receptor for Middle East respiratory syndrome coronavirus (MERS-CoV), and protein modeling suggests that it may play a similar role with SARS-CoV-2, the virus responsible for COVID-19.

Ambry Genetics

Jul 09, 2021

The c.1582A>G (p.M528V) alteration is located in exon 19 (coding exon 19) of the DPP4 gene. This alteration results from a A to G substitution at nucleotide position 1582, causing the methionine (M) at amino acid position 528 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
