Genes affected

TEC (HGNC:11719): (tec protein tyrosine kinase) The protein encoded by this gene belongs to the Tec family of non-receptor protein-tyrosine kinases containing a pleckstrin homology domain. Tec family kinases are involved in the intracellular signaling mechanisms of cytokine receptors, lymphocyte surface antigens, heterotrimeric G-protein coupled receptors, and integrin molecules. They are also key players in the regulation of the immune functions. Tec kinase is an integral component of T cell signaling and has a distinct role in T cell activation. This gene may be associated with myelodysplastic syndrome. [provided by RefSeq, Jul 2008]

Aug 16, 2022

The c.1857A>G (p.I619M) alteration is located in exon 18 (coding exon 17) of the TEC gene. This alteration results from a A to G substitution at nucleotide position 1857, causing the isoleucine (I) at amino acid position 619 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
