Genes affected

SRGAP1 (HGNC:17382): (SLIT-ROBO Rho GTPase activating protein 1) The protein encoded by this gene is a GTPase activator, working with the GTPase CDC42 to negatively regulate neuronal migration. The encoded protein interacts with the transmembrane receptor ROBO1 to inactivate CDC42. [provided by RefSeq, Sep 2016]
