Thousands of genetic variants in protein-coding genes have been linked to disease. However, the functional impact of most variants is unknown as they occur within intrinsically disordered protein regions that have poorly defined functions1-3 . Intrinsically disordered regions can mediate phase separation and the formation of biomolecular condensates, such as the nucleolus4,5 . This suggests that mutations in disordered proteins may alter condensate properties and function6-8 . Here we show that a subset of disease-associated variants in disordered regions alter phase separation, cause mispartitioning into the nucleolus and disrupt nucleolar function...
