Genes affected

CTSO (HGNC:2542): (cathepsin O) The protein encoded by the gene is a cysteine proteinase and a member of the papain superfamily. This proteolytic enzyme is involved in cellular protein degradation and turnover. The recombinant form of this enzyme was shown to degrade synthetic peptides typically used as substrates for cysteine proteinases and its proteolytic activity was abolished by an inhibitor of cyteine proteinase.

Ambry Genetics

Jul 14, 2021

The c.128C>T (p.A43V) alteration is located in exon 1 (coding exon 1) of the CTSO gene. This alteration results from a C to T substitution at nucleotide position 128, causing the alanine (A) at amino acid position 43 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
