Medical genomics is rapidly moving into mainstream medicine, with new and emerging technologies such as molecular genetic diagnostic tests and gene therapy having an unprecedented impact on medicine. There is the urgent need for physicians and medical students to understand these developments and their evolving roles in the post-genomics era. This book is designed to fill that need, and was in fact the first to provide a basic yet thorough introduction to genomics, focusing on its impact on medical research and practice. The new edition has been painstakingly updated and significantly enlarged, with six all-new chapters dealing with many of the most exciting and rapidly developing topics in biomedical research such as multilocus SNP genotyping (SNP chips), RNAi, ChIP-chip, and genomic tiling arrays.
