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]

Ambry Genetics

Feb 12, 2024

The c.197T>C (p.F66S) alteration is located in exon 3 (coding exon 2) of the CPVL gene. This alteration results from a T to C substitution at nucleotide position 197, causing the phenylalanine (F) at amino acid position 66 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
