Genes affected

DPP7 (HGNC:14892): (dipeptidyl peptidase 7) The protein encoded by this gene is a post-proline cleaving aminopeptidase expressed in quiescent lymphocytes. The resting lymphocytes are maintained through suppression of apoptosis, a state which is disrupted by inhibition of this novel serine protease. The enzyme has strong sequence homology with prolylcarboxypeptidase and is active at both acidic and neutral pH. [provided by RefSeq, Jul 2008]

The c.1234T>A (p.F412I) alteration is located in exon 11 (coding exon 11) of the DPP7 gene. This alteration results from a T to A substitution at nucleotide position 1234, causing the phenylalanine (F) at amino acid position 412 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
