Genes affected
CPA2 (HGNC:2297): (carboxypeptidase A2) Three different forms of human pancreatic procarboxypeptidase A have been isolated. The encoded protein represents the A2 form, which is a monomeric protein with different biochemical properties from the A1 and A3 forms. The A2 form of pancreatic procarboxypeptidase acts on aromatic C-terminal residues and is a secreted protein. [provided by RefSeq, Dec 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 28, 2021The c.251A>G (p.Q84R) alteration is located in exon 3 (coding exon 3) of the CPA2 gene. This alteration results from a A to G substitution at nucleotide position 251, causing the glutamine (Q) at amino acid position 84 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
