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]

The c.764G>A (p.S255N) alteration is located in exon 9 (coding exon 8) of the TEC gene. This alteration results from a G to A substitution at nucleotide position 764, causing the serine (S) at amino acid position 255 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
