Explains genetic counselling as a communication process that covers the medical, genetic and psychosocial aspects of a disorder and the assessment of risk. It sets out the main goals, indications, and prospective versus retrospective counselling, then walks through the basic steps from collecting family history to risk assessment, education, decision-making support and follow-up. Mendelian, empirical and modified risk estimates are listed, along with the genetic tests used and the psychological and ethical principles, special situations such as prenatal, cancer and paediatric counselling, and its limitations.
