Genes affected

CTSH (HGNC:2535): (cathepsin H) The protein encoded by this gene is a lysosomal cysteine proteinase important in the overall degradation of lysosomal proteins. It is composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. The encoded protein, which belongs to the peptidase C1 protein family, can act both as an aminopeptidase and as an endopeptidase. Increased expression of this gene has been correlated with malignant progression of prostate tumors. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jan 2016]

The c.209A>G (p.N70S) alteration is located in exon 3 (coding exon 3) of the CTSH gene. This alteration results from a A to G substitution at nucleotide position 209, causing the asparagine (N) at amino acid position 70 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
