RESUMO
The discoveries on molecular aspects of cellular function are changing the concepts of health and disease. All medical fields, including cardiology, have been enriched with several diagnostic test to determine predisposition and to detect molecular dysfunctions. This review on the genetic and molecular aspects of cardiovascular diseases is written at the Centenary of the rediscovery of Mendel's principles on heredity and at the time of the announcement of the end of the human genome sequencing task. The review starts with considerations on the pluricellular constitution of the human body, and the principles of genetics with their molecular bases; including a short description of the methods for gene mapping. The following sections give a historic synopsis on the concepts of medical genetics, molecular medicine, and the Human Genome Project. The review ends with a brief description of the spectrum of genetic diseases, using examples of cardiovascular diseases.
