a Distribution of DDX3X mutants in this study across cBioPortal samples and ten studies of DDX3X-related neurodevelopmental disorders. The number of patient samples in which the mutations at the position of each mutant appeared, in addition to mutations at positions within three amino acids of our selected mutants, were counted. b Proposed working model. DDX3X mutants that disrupt ATPase and strand release activities form hollow condensates in cells without external stress, while mutants that do not disrupt those catalytic steps remain diffuse. The severity of disease related to these mutations is correlated with the dynamics of these condensates. When coexpressed with WT DDX3X, hollow condensates are more dynamic than when coexpressed with DDX3Y, which may explain sex bias in DDX3X-related diseases. Created in BioRender.
