π Understanding Genetic Counseling Sessions
Genetic counseling is a communication process that addresses the human concerns associated with the risk of a genetic disorder occurring in a family. It involves interpreting family and medical histories to assess recurrence risks, educating about inheritance, testing, management, prevention, resources and research.
π History and Background
The field emerged in the mid-20th century, initially focused on providing information about inherited conditions. As genetic testing advanced, the scope broadened to include risk assessment, emotional support, and ethical considerations. The National Society of Genetic Counselors (NSGC) was founded in 1979, establishing professional standards and promoting the field.
