Types of Genetic Diseases

Gene mutations and other chromosomal abnormalities can alter how a specific organ works, change how a baby develops, and cause various other health problems.

Common genetic disorders include:
  • Cystic fibrosis. Certain cells produce a thick mucus, which can lead to life-threatening complications.
  • Ataxia. The nervous system cannot control normal muscle movement.
  • Muscular dystrophy. Problems with the skeletal muscles that control movement.
  • Down syndrome. Caused by an extra copy of chromosome 21, which results in changes in facial features, poor muscle tone, and intellectual disability.
  • Sickle cell anemia. A blood disorder caused by abnormal red blood cells and hemoglobin.
  • Rett syndrome. Normal early development and growth followed by declines in intellectual ability and physical movement.


Causes of Genetic Disorders

Genetic disorders are caused by a chromosomal abnormality or an unusual gene. A small change in just one gene can affect the function of the body. Most genetic disorders are passed down from parent to child (inherited).

Some genetic disorders are the result of a new, spontaneous gene mutation. The mutation could be present in either the sperm or egg, even though the parent does not have the genetic disorder. New mutations also can occur throughout our lifetime, anytime after a pregnancy begins.

Other genetic disorders are caused by more than one factor (multifactorial). For example, cancer is a multifactorial genetic disorder. People can inherit genes that increase the risk of cancer, but they may not get the disease unless they are also exposed to certain environmental factors.
