A single gene that was previously found to be the driving force in a rare syndrome linked to epilepsy, autism and developmental disability has been identified as a linchpin in the formation of healthy neurons. Researchers say the gene, DDX3X, forms a cellular machine called a helicase, whose job it is to split open the hairpins and cul-de-sacs of RNA so that its code can be read by the protein-making machinery of the cell.
