Genes affected

ARHGAP26 (HGNC:17073): (Rho GTPase activating protein 26) Interaction of a cell with the extracellular matrix triggers integrin cell surface receptors to begin signaling cascades that regulate the organization of the actin-cytoskeleton. One of the proteins involved in these cascades is focal adhesion kinase. The protein encoded by this gene is a GTPase activating protein that binds to focal adhesion kinase and mediates the activity of the GTP binding proteins RhoA and Cdc42. Defects in this gene are a cause of juvenile myelomonocytic leukemia (JMML). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2017]

The c.59A>G (p.E20G) alteration is located in exon 1 (coding exon 1) of the ARHGAP26 gene. This alteration results from a A to G substitution at nucleotide position 59, causing the glutamic acid (E) at amino acid position 20 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
