Genes affected

CTSW (HGNC:2546): (cathepsin W) The protein encoded by this gene, a member of the peptidase C1 family, is a cysteine proteinase that may have a specific function in the mechanism or regulation of T-cell cytolytic activity. The encoded protein is found associated with the membrane inside the endoplasmic reticulum of natural killer and cytotoxic T-cells. Expression of this gene is up-regulated by interleukin-2.

The c.532G>T (p.V178L) alteration is located in exon 5 (coding exon 5) of the CTSW gene. This alteration results from a G to T substitution at nucleotide position 532, causing the valine (V) at amino acid position 178 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
