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

Apr 26, 2023

The c.1901C>T (p.T634M) alteration is located in exon 13 (coding exon 13) of the CPXM1 gene. This alteration results from a C to T substitution at nucleotide position 1901, causing the threonine (T) at amino acid position 634 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
