Genes affected

GAB3 (HGNC:17515): (GRB2 associated binding protein 3) This gene is a member of the GRB2-associated binding protein gene family. These proteins are scaffolding/docking proteins that are involved in several growth factor and cytokine signaling pathways, and they contain a pleckstrin homology domain, and bind SHP2 tyrosine phosphatase and GRB2 adapter protein. The protein encoded by this gene facilitates macrophage differentiation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.
