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 GeneticsNov 09, 2021The c.1576G>A (p.D526N) alteration is located in exon 11 (coding exon 11) of the CPXM1 gene. This alteration results from a G to A substitution at nucleotide position 1576, causing the aspartic acid (D) at amino acid position 526 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
