Please enable it to take advantage of the complete set of features! Epub 2017 Mar 2. The application of next-generation sequencing (NGS) technologies in cancer research has accelerated the discovery of somatic mutations; however, progress in the identification of germline variation associated with cancer risk is less clear. Whole exome sequencing for the diagnosis of phenotypic disorder patients was utilized in a study of 250 unselected, referred patients who had previously undergone extensive rare genetic disease diagnostic testing, with a 24.8% (62/250) molecular diagnosis rate of autosomal dominant (n = 33), autosomal recessive (n = 16), and X-linked (n = 9) diseases.
