Genes affected
CPB1 (HGNC:2299): (carboxypeptidase B1) Three different procarboxypeptidases A and two different procarboxypeptidases B have been isolated. The B1 and B2 forms differ from each other mainly in isoelectric point. Carboxypeptidase B1 is a highly tissue-specific protein and is a useful serum marker for acute pancreatitis and dysfunction of pancreatic transplants. It is not elevated in pancreatic carcinoma.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.571A>G (p.R191G) alteration is located in exon 6 (coding exon 6) of the CPB1 gene. This alteration results from a A to G substitution at nucleotide position 571, causing the arginine (R) at amino acid position 191 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
