Some people inherit genetic disorders from the parents, while acquired changes or mutations in a
preexisting gene or group of
genes cause other genetic diseases. Genetic mutations can occur either randomly or due to some environmental exposure.

Are all genetic disorders inherited?
However not all genetic conditions are passed down from your parents, some gene changes occur randomly before you are born. Many health conditions run in families. Genetic conditions are often called
hereditary
because they can be passed from parents to their children.
Can genetic disorders be cured?
Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and
most cannot be cured
. However, approaches may be available to treat or manage some of the associated signs and symptoms.

mitochondrial DNA
comes only from the mother.

specializes in using genetic information and DNA tests to diagnose, treat, manage or prevent inherited genetic disorders, chromosome defects, and diseases and conditions influenced by genetic factors.
What is the only way to cure a genetic disease?
