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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.1483C>T (p.H495Y) alteration is located in exon 9 (coding exon 9) of the TSKS gene. This alteration results from a C to T substitution at nucleotide position 1483, causing the histidine (H) at amino acid position 495 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
