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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.1325A>G (p.D442G) alteration is located in exon 8 (coding exon 8) of the TSKS gene. This alteration results from a A to G substitution at nucleotide position 1325, causing the aspartic acid (D) at amino acid position 442 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
