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.1171G>A (p.V391M) alteration is located in exon 12 (coding exon 11) of the CPVL gene. This alteration results from a G to A substitution at nucleotide position 1171, causing the valine (V) at amino acid position 391 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
