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]

The c.399G>C (p.M133I) alteration is located in exon 4 (coding exon 3) of the CPVL gene. This alteration results from a G to C substitution at nucleotide position 399, causing the methionine (M) at amino acid position 133 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
