Passenger
Passenger (Medicine)
Passenger (pronounced: /ˈpasɪndʒər/), in the context of medicine, refers to a gene or mutation that is present in a cell but does not contribute to the cancerous or diseased state of the cell. The term is often used in contrast to driver genes or mutations, which are directly responsible for the development of a disease.
Etymology
The term "passenger" comes from the English word for a person who travels in a vehicle but does not operate it. In the medical context, it is used metaphorically to describe genes or mutations that are carried along in a cell without affecting its function.
