penetrance - (pronounced) (PEH-neh trunks) Describes how likely it is that a person who has a specific disease-causing mutation (change) in a gene will show signs and symptoms of the disease. Not everyone who has the mutation will develop the disease. For example, some people with a mutation in the BRCA1 or BRCA2 gene will develop cancer in their lifetime, while others will not.

Complete penetrance means that any person who has the mutation will show signs and symptoms of the disease
