Genomic imprinting results in the preferential expression of one gene, depending on the parent of origin, and it is associated with several disease syndromes in humans. This book covers a wealth of research material on chromatin structure, epigenetics, clinical genetics, developmental biology, cancer, hypotheses of evolution, and the molecular basis of the imprinting process, which will help explain not only the mechanisms of genomic imprinting, but also its biological and medical consequences.
