Mutations in the CCM3 gene in humans lead to severe forms of cerebral cavernous malformation. Here, Lant et al. shed light on the mechanism of CCM-3 function in C. elegans, and show that CCM-3 ablation leads to defects in excretory canal extension and the formation of cysts reminiscent of human malformations.
