Genes affected

TNK1 (HGNC:11940): (tyrosine kinase non receptor 1) The protein encoded by this gene belongs to the tyrosine protein kinase family. Tyrosine protein kinases are important regulators of intracellular signal transduction pathways, mediating cellular proliferation, survival, and development. This gene is highly expressed in fetal tissues and at lower levels in few adult tissues, thus may function in signaling pathways utilized broadly during fetal development, and more selectively in adult tissues. It plays a negative regulatory role in the Ras-Raf1-MAPK pathway, and knockout mice have been shown to develop spontaneous tumors, suggesting a role as a tumor suppressor gene. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Collection Method: clinical testing

The c.575T>C (p.L192P) alteration is located in exon 5 (coding exon 4) of the TNK1 gene. This alteration results from a T to C substitution at nucleotide position 575, causing the leucine (L) at amino acid position 192 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
