Genes affected

CPD (HGNC:2301): (carboxypeptidase D) The metallocarboxypeptidase family of enzymes is divided into 2 subfamilies based on sequence similarities. The pancreatic carboxypeptidase-like and the regulatory B-type carboxypeptidase subfamilies. Carboxypeptidase D has been identified as a regulatory B-type carboxypeptidase. CPD is a homolog of duck gp180, a hepatitis B virus-binding protein. Transcript variants utilizing alternative polyadenylation signals exist for this gene. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.412A>G (p.M138V) alteration is located in exon 1 (coding exon 1) of the CPD gene. This alteration results from a A to G substitution at nucleotide position 412, causing the methionine (M) at amino acid position 138 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
