Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BA1

The NM_001871.3(CPB1):​c.622G>A​(p.Asp208Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.232 in 1,612,786 control chromosomes in the GnomAD database, including 44,685 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D208A) has been classified as Uncertain significance.

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.
