Genes affected

GAB2 (HGNC:14458): (GRB2 associated binding protein 2) This gene is a member of the GRB2-associated binding protein (GAB) gene family. These proteins contain pleckstrin homology (PH) domain, and bind SHP2 tyrosine phosphatase and GRB2 adapter protein. They act as adapters for transmitting various signals in response to stimuli through cytokine and growth factor receptors, and T- and B-cell antigen receptors. The protein encoded by this gene is the principal activator of phosphatidylinositol-3 kinase in response to activation of the high affinity IgE receptor. Two alternatively spliced transcripts encoding different isoforms have been described for this gene. [provided by RefSeq, Nov 2009]

The c.941T>C (p.M314T) alteration is located in exon 4 (coding exon 4) of the GAB2 gene. This alteration results from a T to C substitution at nucleotide position 941, causing the methionine (M) at amino acid position 314 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
