Genes affected
CPA5 (HGNC:15722): (carboxypeptidase A5) Carboxypeptidases have functions ranging from digestion of food to selective biosynthesis of neuroendocrine peptides. Members of the A/B subfamily of carboxypeptidases, such as CPA5, contain an approximately 90-amino acid pro region that assists in the folding of the active carboxypeptidase domain. Cleavage of the pro region activates the enzyme (Wei et al., 2002 [PubMed 11836249]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2024The c.822G>C (p.W274C) alteration is located in exon 11 (coding exon 8) of the CPA5 gene. This alteration results from a G to C substitution at nucleotide position 822, causing the tryptophan (W) at amino acid position 274 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
