Genetic Disorders

Mutations or problematic changes in your DNA can cause genetic disorders. Proper diagnosis, preventive measures and treatment can help manage symptoms and prevent complications. This allows people with a variety of genetic conditions to live productive, full lives.

Some gene mutations are passed down from parents. Other times, a genetic condition can happen spontaneously to one individual in a family. In some cases, lifestyle and environmental factors can cause mutations, leading to an acquired genetic disorder.

Common types of genetic disorders

  • Single-gene disorders (e.g., sickle cell anemia) are caused by mutations in just one gene.
  • Chromosomal disorders (e.g. Down syndrome) are due to having missing or extra chromosomes or chromosomes with structural changes. 
  • Complex disorders (e.g., hereditary colon cancer) can result from one or more genes with a mutation, in addition to the effects of lifestyle and environment.

Genetic tests

The benefits of genetic testing include the following:

  • Accurately diagnosing a person who has symptoms of a genetic disease.
  • Revealing genetic diseases in adults and children before they cause any symptoms, allowing for preventive maintenance and care.
  • Helping doctors decide the best course of treatment for specific genetic diseases.
  • Identifying a genetic disease during pregnancy.
  • Determining if parents might be gene carriers for a disease that could affect their children.
