Clinical Genomics provides an overview of the various next-generation sequencing (NGS) technologies that are currently used in clinical diagnostic laboratories. It presents key bioinformatic challenges and the solutions that must be addressed by clinical genomicists and genomic pathologists, such as specific pipelines for identification of the full range of variants that are clinically important.

This book is also focused on the challenges of diagnostic interpretation of NGS results in a clinical setting. Its final sections are devoted to the emerging regulatory issues that will govern clinical use of NGS, and reimbursement paradigms that will affect the way in which laboratory professionals get paid for the testing.

Key Features

  • Simplifies complexities of NGS technologies for rapid education of clinical genomicists and genomic pathologists towards genomic medicine paradigm
  • Tried and tested practice-based analysis for precision diagnosis and treatment plans
  • Specific pipelines and meta-analysis for full range of clinically important variants


Clinical Genomicists, Molecular Pathologists, molecular Geneticists, clinical Cytogeneticists, Clinical Geneticists, Primary Care Physicians (including Oncologists, Pediatricians, Neurologists, Cardiologists, and Neonatologists) and Genetic Counselors seeking to use or interpret Next Gen Sequencing in the diagnosis, prognosis, and management of inherited and somatic disorders in the era of precision medicine.
