Genetic testing is a medical laboratory test that examines your genes. Genes are DNA instructions that we all inherit from our parents. Diﬀerent“ mistakes” in our genes, called mutations, can cause diﬀerent diseases. Some of these diseases are rare, like cystic ﬁbrosis or Huntington’s disease; others are common, like cancer. Genetic tests can be used to conﬁrm the diagnosis or give you information about possible development of a disease.
