SDH5 Mutations and Familial Paraganglioma: Somewhere Warburg is Smiling

Paragangliomas have been linked to mutations affecting the succinate dehydrogenase complex. In a recent issue of Science, Rutter and coworkers showed that SDH5 is required for the flavination of SDHA, which is necessary for SDH assembly and function. Moreover, they detected SDH5 mutations in a large kindred with familial paraganglioma.
