Is Genetic the same as hereditary?

Because hereditary diseases are caused by genetic mutations, you may see the terms “hereditary” and “genetic” used interchangeably when referring to inherited disease. But while a genetic disease is also the result of a gene mutation, it may or may not be hereditary.

Can a disease be hereditary?

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.

How do they test for genetic disorders?

Most of the time, genetic disorders are diagnosed through a specific test, which can include examining chromosomes or DNA (the tiny proteins that make up genes), or testing the blood for certain enzymes that may be abnormal. Studying enzymes is called biochemical genetic testing.
