Genes affected
CTSZ (HGNC:2547): (cathepsin Z) The protein encoded by this gene is a lysosomal cysteine proteinase and member of the peptidase C1 family. It exhibits both carboxy-monopeptidase and carboxy-dipeptidase activities. The encoded protein has also been known as cathepsin X and cathepsin P. This gene is expressed ubiquitously in cancer cell lines and primary tumors and, like other members of this family, may be involved in tumorigenesis. [provided by RefSeq, Oct 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2023The c.826G>A (p.V276M) alteration is located in exon 6 (coding exon 6) of the CTSZ gene. This alteration results from a G to A substitution at nucleotide position 826, causing the valine (V) at amino acid position 276 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
