Genes affected

DPP8 (HGNC:16490): (dipeptidyl peptidase 8) This gene encodes a member of the peptidase S9B family, a small family of dipeptidyl peptidases that are able to cleave peptide substrates at a prolyl bond. The encoded protein shares similarity with dipeptidyl peptidase IV in that it is ubiquitously expressed, and hydrolyzes the same substrates. These similarities suggest that, like dipeptidyl peptidase IV, this protein may play a role in T-cell activation and immune function. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

Nov 30, 2021

The c.1948C>T (p.L650F) alteration is located in exon 16 (coding exon 15) of the DPP8 gene. This alteration results from a C to T substitution at nucleotide position 1948, causing the leucine (L) at amino acid position 650 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
