Genetic tests, such as GeneSeeker, analyze genes, which are chemical instructions encoded in our DNA. The genes are the blueprints for building our bodies and maintaining the health of our cells, tissues and organs. Genetic testing looks for variations in your genes (mutations) that can cause genes to stop working properly, potentially lead to disease. There are various reasons why you or your healthcare provider might consider genetic testing, such as assessing the risk of you and your partner having a child affected by an inherited disorder, or to determine the cause of an inherited condition that runs in your family.
