Inherited ataxias are difficult to diagnose genetically. Pyle et al. use whole-exome sequencing to provide a likely molecular diagnosis in 14 of 22 families with ataxia. The approach reveals de novo mutations, broadens the phenotype of other disease genes, and is equally effective in young and older-onset patients.
