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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.1111T>G (p.L371V) alteration is located in exon 11 (coding exon 10) of the CPVL gene. This alteration results from a T to G substitution at nucleotide position 1111, causing the leucine (L) at amino acid position 371 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
