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 GeneticsSep 01, 2021The c.533T>A (p.I178N) alteration is located in exon 3 (coding exon 2) of the CPQ gene. This alteration results from a T to A substitution at nucleotide position 533, causing the isoleucine (I) at amino acid position 178 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
