Biallelic TRIP13 mutations predispose to Wilms tumor and chromosome missegregation

Nazneen Rahman, Geert Kops and colleagues report the identification of biallelic loss-of-function mutations in TRIP13 in six individuals with Wilms tumor who presented with features of mosaic variegated aneuploidy. They show that TRIP13-mutant cells show spindle assembly checkpoint defects and suggest that mechanisms leading to aneuploidy may contribute directly to increased cancer risk.
