Genetic Diagnosis through Whole-Exome Sequencing

To the Editor: Yang et al. (Oct. 17 issue)(1) report the application of whole-exome sequencing in 250 patients with a potentially genetic disease, which resulted in a molecular diagnosis in 25% of them. A total of 30 patients had medically actionable incidental findings in a total of 16 genes; 18 of these patients had genotypes that the American College of Medical Genetics and Genomics has recommended be reported to the ordering physician.(2) As noted in the editorial by Jacob,(3) reporting these incidental findings is a gray area.
