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.1556A>G (p.K519R) alteration is located in exon 18 (coding exon 18) of the ARHGAP26 gene. This alteration results from a A to G substitution at nucleotide position 1556, causing the lysine (K) at amino acid position 519 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
