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 GeneticsMay 11, 2022The c.185G>A (p.R62K) alteration is located in exon 2 (coding exon 1) of the CPQ gene. This alteration results from a G to A substitution at nucleotide position 185, causing the arginine (R) at amino acid position 62 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
