Genes affected

CPM (HGNC:2311): (carboxypeptidase M) The protein encoded by this gene is a membrane-bound arginine/lysine carboxypeptidase. Its expression is associated with monocyte to macrophage differentiation. This encoded protein contains hydrophobic regions at the amino and carboxy termini and has 6 potential asparagine-linked glycosylation sites. The active site residues of carboxypeptidases A and B are conserved in this protein. Three alternatively spliced transcript variants encoding the same protein have been described for this gene.

The c.932T>C (p.V311A) alteration is located in exon 7 (coding exon 6) of the CPM gene. This alteration results from a T to C substitution at nucleotide position 932, causing the valine (V) at amino acid position 311 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
