Book excerpt: Molecular Genetic Pathology, Second Edition presents up-to-date material containing fundamental information relevant to the clinical practice of molecular genetic pathology. Fully updated in each area and expanded to include identification of new infectious agents (H1N1), new diagnostic biomarkers and biomarkers for targeted cancer therapy. This edition is also expanded to include the many new technologies that have become available in the past few years such as microarray (AmpliChip) and high throughput deep sequencing, which will certainly change the clinical practice of molecular genetic pathology. Part I examines the clinical aspects of molecular biology and technology, genomics. Poharmacogenomics and proteomics, while Part II covers the clinically relevant information of medical genetics, hematology, transfusion medicine, oncology, and forensic pathology. Supplemented with many useful figures and presented in a helpful bullet-point format, Molecular Genetic Pathology, Second Edition provides a unique reference for practicing pathologists, oncologists, internists, and medical genetisists. Furthermore, a book with concise overview of the field and highlights of clinical applications will certainly help those trainees, including pathology residents, genetics residents, molecular pathology fellows, internists, hematology/oncology fellows, and medical technologists in preparing for their board examination/certification.
