Dominant truncating variants in KAT6A cause two neurodevelopmental disorders with opposite gene regulatory and metabolic changes.

Using patient-derived iPSCs and multi-omics profiling, it is demonstrated that early-truncating variants cause loss-of-function via nonsense-mediated decay (NMD), while late-truncating variants that escape NMD cause gain-of-function effects.
