Only phenotypic categories that comprised more than five individuals are included. Abbreviations: CNS, central nervous system; DD, developmental delay; ID, intellectual disability; NA, not applicable; NCGENES, North Carolina Clinical Genomic Evaluation by Next-Generation Exome Sequencing. “(?)” indicates a lack in clarity regarding exactly which diseases are included in a particular described phenotype, and reflects our best guess as to what the category included. “#” indicates that phenotypes in particular categories were reported in the study but did not include more than five individuals.
