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]

The c.346G>A (p.G116S) alteration is located in exon 4 (coding exon 4) of the CPA2 gene. This alteration results from a G to A substitution at nucleotide position 346, causing the glycine (G) at amino acid position 116 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
