A genetic disorder is a health condition caused by an abnormal chromosome or gene. Genes are passed down from parent to child and contain the “building instructions” for the human body. An alteration or other change in a gene is called a mutation.

Signs and symptoms of genetic disorders vary greatly depending upon which parts of the body are affected. Prenatal screening and testing can detect many genetic disorders.
Some genetic disorders do not have any visible or obvious signs or symptoms. Babies born in the US undergo newborn screening to check for the presence of certain genetic disorders and other health conditions.
Genetic disorders are caused by an unusual gene or a chromosomal abnormality. A small change in just one gene can affect the function of the body. Most genetic disorders are inherited, passed down from parent to child through generations.
Some genetic disorders are the result of a new, spontaneous gene mutation. A new mutation can occur in the egg or sperm that creates a child, even though the parent does not have the genetic disorder. New mutations can also occur throughout our lifetimes. Still, other genetic disorders are caused by more than one factor (multifactorial).
At present, there is no known cure for genetic disorders because doctors can’t correct abnormal genes. Treatment focuses on preventing complications and improving health. Genetic counselors can help couples understand their risk of passing down a genetic disorder. Your doctor is your best source of information about genetic disorder treatment alternatives and expected health outcomes.
Dignity Health provides compassionate treatment of genetic disorders in Arizona.
