Abstract
Genetic testing has undergone a revolution in the last decade, particularly with the advent of next-generation sequencing and its associated reductions in costs and increases in efficiencies. The Undiagnosed Diseases Network (UDN) has been a leader in the application of such genomic testing for rare disease diagnosis. This review discusses the current state of genomic testing performed within the UDN, with a focus on the strengths and limitations of whole-exome and whole-genome sequencing in clinical diagnostics and the importance of ongoing data reanalysis. The role of emerging technologies such as RNA and long-read sequencing to further improve diagnostic rates in the UDN is also described. This review concludes with a discussion of the challenges faced in insurance coverage of comprehensive genomic testing as well as the opportunities for a larger role of testing in clinical medicine.
期刊介绍：
The Annual Review of Medicine, which has been published since 1950, focuses on important advancements in diverse areas of medicine. These include AIDS/HIV, cardiology, clinical pharmacology, dermatology, endocrinology/metabolism, gastroenterology, genetics, immunology, infectious disease, neurology, oncology/hematology, pediatrics, psychiatry, pulmonology, reproductive medicine, and surgery. The journal's current volume has transitioned from a gated access model to an open access model through the Annual Reviews' Subscribe to Open program. All articles published in the journal are now available under a CC BY license.
