Genes affected

CPXM1 (HGNC:15771): (carboxypeptidase X, M14 family member 1) This gene likely encodes a member of the carboxypeptidase family of proteins. Cloning of a comparable locus in mouse indicates that the encoded protein contains a discoidin domain and a carboxypeptidase domain, but the protein appears to lack residues necessary for carboxypeptidase activity.[provided by RefSeq, May 2010]

Ambry Genetics

Jul 15, 2021

The c.2057G>A (p.R686Q) alteration is located in exon 14 (coding exon 14) of the CPXM1 gene. This alteration results from a G to A substitution at nucleotide position 2057, causing the arginine (R) at amino acid position 686 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
