Genes affected
CPVL (HGNC:14399): (carboxypeptidase vitellogenic like) The protein encoded by this gene is a carboxypeptidase and bears strong sequence similarity to serine carboxypeptidases. Carboxypeptidases are a large class of proteases that act to cleave a single amino acid from the carboxy termini of proteins or peptides. The exact function of this protein, however, has not been determined. [provided by RefSeq, Jan 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.1259A>C (p.K420T) alteration is located in exon 12 (coding exon 11) of the CPVL gene. This alteration results from a A to C substitution at nucleotide position 1259, causing the lysine (K) at amino acid position 420 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
