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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2022The c.108A>G (p.I36M) alteration is located in exon 2 (coding exon 1) of the CPQ gene. This alteration results from a A to G substitution at nucleotide position 108, causing the isoleucine (I) at amino acid position 36 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
