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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.1933G>A (p.V645M) alteration is located in exon 13 (coding exon 13) of the CPXM1 gene. This alteration results from a G to A substitution at nucleotide position 1933, causing the valine (V) at amino acid position 645 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
