Badcock sets out a radical new theory of the mind based on the recent discovery of genomic imprinting. He uses psychiatric case material to show how many of the symptoms of psychosis can be shown to be the mental mirror-images of those of autism. This new theory casts intriguing new light on topics such as the nature of genius.

Genomic imprinting refers to a recently discovered phenomenon in which the expression pattern of an allele depends on whether that allele was inherited from the mother or the father. This difference in expression strategy correlates with differences in the epigenetic state of the two alleles. These epigenetic differences include DNA methylation at CpG dinucleotides, as well as modifications on the histones associated with the locus. In the simplest possible cases, the promoter region of the imprinted gene is methylated during oogenesis, but not spermatogenesis (or vice versa). This methylation (and its accompanying histone modifications) results in inactivation of the modified allele. Of course, most imprinted genes do not fall into this simplest case. The goal of this book is neither to provide a basic introduction to imprinting, nor to provide a comprehensive survey of the current state of the field (which would necessarily span multiple books). Rather, the book covers on some of the more recent advances, with the goal of drawing attention to some of the emerging subtleties and complexities associated with imprinted genes.

Imprinted genes, many of which generally control growth and development, frequently lose their imprints during cancer progression, a loss that then plays a substantial role in uncontrolled tumor growth. Imprint instability also appears to be a major limitation to the success of mammalian cloning experiments. In Genomic Imprinting: Methods and Protocols, Andrew Ward and a team of experienced researchers have brought together a collection of optimized classic and vanguard techniques for the identification and analysis of imprinted genes. The majority of protocols describe molecular techniques that allow examination of gene structure or expression in an allele-specific manner. Protocols are included for identifying and cloning imprinted genes, for analyzing imprinted gene expression, for the study of DNA methylation and methylation-sensitive DNA-binding proteins, and for examining chromatin structure. There are also methods for the manipulation of mouse embryos to produce monoparental embryos and embryonic stem cells, and for the generation of transgenic mice with BAC, PAC, and YAC constructs. Each technique is described in step-by-step detail to ensure successful results. Incorporating a wealth of knowledge from leading exponents in the field, Genomic Imprinting: Methods and Protocols brings together all the essential molecular, genetic, and embryological methods commonly used in today's laboratories for the identification and analysis of imprinted genes.
