The ENS regulates all essential gut functions, such as motility, nutrient uptake, immune response, and microbiota colonization. Deficits in ENS neuron numbers and composition cause debilitating gut dysfunction. Yet, few studies have identified genes that control neuronal differentiation and the generation of the diverse neuronal subtypes in the ENS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Utilizing existing CRISPR\/Cas9 genome editing technology in zebrafish, we have developed a rapid and scalable screening approach for identifying genes that regulate ENS neurogenesis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Key Results<\/jats:title><jats:p>As a proof\u2010of\u2010concept, F0 guide RNA\u2010injected larvae (F0 crispants) targeting the known ENS regulator genes <jats:italic>sox10<\/jats:italic>, <jats:italic>ret<\/jats:italic>, or <jats:italic>phox2bb<\/jats:italic> phenocopied known ENS phenotypes with high efficiency. We evaluated 10 transcription factor candidate genes as regulators of ENS neurogenesis and function. F0 crispants for five of the tested genes have fewer ENS neurons.
