The originally published version of this Article contained errors in Figure 1. In panel c, the grey shading denoting evolutionary conservation and the arrowheads indicating amino acids affected in Snyder-Robinson syndrome were displaced relative to the sequence. These errors have now been corrected in both the PDF and HTML versions of the manuscript.
