Genes affected

CPQ (HGNC:16910): (carboxypeptidase Q) This gene encodes a metallopeptidase that belongs to the peptidase M28 family. The encoded protein may catalyze the cleavage of dipeptides with unsubstituted terminals into amino acids. [provided by RefSeq, Jul 2013]

Apr 15, 2024

The c.563C>T (p.T188M) alteration is located in exon 3 (coding exon 2) of the CPQ gene. This alteration results from a C to T substitution at nucleotide position 563, causing the threonine (T) at amino acid position 188 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
