Genes affected

TSKS (HGNC:30719): (testis specific serine kinase substrate) This gene may play a role in testicular physiology, spermatogenesis or spermiogenesis. Expression of the encoded protein is highest in the testis and down-regulated in testicular cancer. The gene is localized to the region 19q13.3 among the related RAS viral oncogene homolog (RRAS) and interferon regulatory factor 3 (IRF3) genes, which are both involved in tumorigenesis pathways and progression.

The c.1076G>A (p.G359D) alteration is located in exon 7 (coding exon 7) of the TSKS gene. This alteration results from a G to A substitution at nucleotide position 1076, causing the glycine (G) at amino acid position 359 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
