The clinical relevance of the Human Genome Project and next‐generation sequencing technology was demonstrated for the first time in 2009, when whole‐exome sequencing (WES) provided the definitive diagnosis of congenital chloride diarrhea in an infant with presumed renal salt‐wasting disease. Over the past decade, numerous studies have shown the utility of WES for clinical diagnosis as well as for discovery of novel genetic disorders through analysis of a single or a handful of informative pedigrees. Hence, advances in improving the speed, accuracy, and computational analysis combined with exponential decrease in the cost of sequencing the human genome is transforming the practice of medicine. The impact of WES has been most noticeable in pediatric disorders and oncology, but its utility in the liver clinic is recently emerging. Here, we assess the current status of WES for clinical diagnosis and acceleration of translation research to enhance care of patients with liver disease.
