List of Genetic Diseases and Disorders

List of Genetic Diseases and Disorders: Genetic diseases and disorders are the result of anomalies in a gene or an entire part of the chromosome of an individual. They may arise due to spontaneous mutations or may be inherited from the parents. The current article provides a list of such genetic diseases and disorders.

Mutations: The Potential Power of a Small Change. Mutations are fascinating occurrences. Deleting a single base or inserting a new one has the potential to create great change. The Amoeba Sisters will discuss the types of gene and chromosome mutations and also explain how mutations can occur. As a real world example, they'll talk about sickle cell anemia and the remarkable difference between having sickle cell anemia and only being a carrier. Come laugh and learn with the Amoeba Sisters!
